I think it would be great instead of signing for every time i make a deposit for a big party just make one big receipt with all the times and amounts on them and just sign once.
Don't think, do. I've negotiated parties with different ladies and paid for all of them at one time with one charge and had the parties later. Some credit card companies will put a temporary "hold" on my card when I use it multiple times for large dollar amounts in the same place or in a short period of time. It can be a pain in the ass to have to call them, but I understand they are attempting to verify that my card wasn't lost or stolen and used by someone else. A decade ago I once accidentally dropped my credit card on the ground when pumping gasoline. By the time I realized it, someone had already used my card to make unauthorized purchases.
