Confused.....

Has this ever happened to you? Because I get VERY angry everytime it happens to me!.....When you are going through a drive-thru and you are the only car in line. You order your food and they say, "Pull ahead to window 1." Well as your trying to get to window 1 you have to reach in your purse/wallet to get your money and the lady is sticking her head out the window to motion that you need to hurry up. How am I suppose to have time to count my money and get it ready in 5 seconds? It's not like I can have my money ready ahead of time because I don't know how much its going to cost. It is just sooooo frustrating!!
