Gah!  It's almost impossible to have fun in drive-thru because of idiocy on the customer's part.  Really, most people are ok.  Most customers are polite and efficient.  But you really remember the idiots.  They stick in your mind.
 

   First, recognize that some people come by and try to annoy you.  It's sorta' funny when you mean to do it rather than blunder along blindly and make me throw hamburgers at you.  So, next time you go out and need a meal, have some fun with these ideas.
 

(1) Stand close to the speaker and yell your order.  Be sure to use colorful language.

(2)  Transparent tape is fun!  Put some over the speaker and watch the order-taker and the customers start speaking in very loud voices.

(3)  Speak a foreign language.  Speak gibberish.  Make up new words as you go along.  Be sure to speak perfect english when you're at the window.  If a manager is there, ask why the order-taker is having so much trouble understanding you.

(4)  Beat them to the punch.  "May I take your order."  Also, stupid jokes make me angry.  Laugh at your own jokes.  A lot.

(5)  I hate confusing items.  "A small regular cone."  "Large orange Coke."  Don't speak clearly.  Be sure to order things that they don't have.  Eggrolls, grilled cheese, and ramen noodles are good examples.

(6)  Idiots do this one.  It's just rude; do not go into a crowded drive-thru line, make an insane 40$+ order, and leave.  It's not funny for anyone.

(7) I hate it when people come to the window and give me cans or bags and ask me to throw them away.  It's especially annoying when it's food items from another restaurant.  Capitalize on this; hand big bags of trash through the window and ask them to throw it out.  Make sure it smells.

(8) Drive through naked.  Bring friends.

(9) Have someone on the hood pay and accept the food.

(10) People on the hood are fun, but people in the trunk are funnier.  Banging loudly and jumping out are just some of the possibilities.

(11) If you have a speaker and a microphone, you can produce feedback by pointing the mic at the speaker and the speaker at the oder-taker.

(12) I know how we act when a hot girl comes through drive-thru.  It's only polite to inform your friends.  Have a female friend talk to the speaker 'suggestively'.  Then have her hide.  Be sure to count the number of fellow employees that were called over.  They will be called over.

(13) Rudeness is totally inappropriate.  But there's nothing wrong with taking your food and just laughing and laughing and laughing at the guy who gave you your order.
 
 
 

   It's more funny to be doing than to have to put up with this crap.  So, when you're on the receiving end of this stuff, here's something to fight back with.
 

(1) Never make eye contact.  Act disgusted.

(2) Alternatively, never break eye contact.  Be sure to stare at them when you should be getting their food.

(3) Suggestive selling helps to increase revenues.  It's less effective when you sell items you don't carry.  "Welcome to DQ, would you like to try a whopper?"

(4) People complain when they don't get ketchup, salt, napkins, and other condiments.  Be sure to offer these things to people no matter what.  "Would you like any hot sauce, mild sauce, or ketchup with your medium Root Beer?"

(5) Another fun condiment idea is to put random objects into customer's bags.  Cup lids, ice, and cookie dough are great examples.

(6) Write notes on the napkins to the customer.  Another example is to write fortunes on the inside of the burger wrappers.  Be grim.

(7) Strange noises on the intercom and in the background make people uneasy.  Try meowing.

(8) Here's an idea I found online: when a customer pays with a twenty dollar bill, hold it against the
light. Then, ask the customer if the money is real. After they reassure you that it is real currency, reply by saying; "Dang."

(9) Wear funny sunglasses.

(10) If you can manage it, speak only in rhyme.

(11) It's always fun to flirt with the customers.  Do so regardless of age and gender.

(12) Ask the customer when they got their vehichle; after they respond, proceed to tell them how you had one just like it that was stolen days before.

(13) Discuss politics.  Regardless of how intelligent this person is.

(14) Always complain about colon problems, arthritis, and other such problems.  It's even better done by by younger workers.
