All the McDonalds around here take take your money and send you on your way while they are taking the order of the person behind you. Probably depends on the place. I have had this issue at McDonald's before. Finally, I had to explain very slowly in great detail that I would pay for the price of an entire kids meal but DO NOT WANT a drink with it, I'll pay for the drink, but I do not want it physically given to me, and then I would like to purchase a separate bottle of water. And yes, I did check the food for spit--lol.
