This is a little trick anyone could do at practically any fast food place to get a free drink, and its much easier than robbing a bank!
Now this can either be done through a drive-through or at the counter, but requires you to have access to the fast food place's trash can. The first thing you are going to want to do is to, with out being obvious, go to one the restaurants trash cans ( one not in site of the employees is best) and pull out any used cup. If you have germ issues this one is not for you! Now that you have you newly acquired old cup, simply go up to the clerk behind the counter* and tell him/her that you got a coke before, and now you want a refill of sprite, however you dont want to mix the two sodas together.
*though this might seem like a weird request, this clerk doesn't give a fuck. They are working in a shitty fast food joint, and some asshole coming up wanting a refill without mixing the new drink in with the old is not worth their struggle. So they will take your dirty old cup, throw it away, and hand you a brand new cup with brand new soda of your choice in it. At this point you can leave. You have successfully got a free drink!
