Actually, I think the purpose is so you DON'T have to carry a bunch of cash with you! I like the idea of this. I will have a receipt for everything & it will be easier for me to compare it to my charge card when I get home. Yes, I will probably have a stroke when I see what I actually spent! But, I don't have to worry about all that cash! Easier for going to the pool, too! No cash to get wet or worry about getting stolen! Just one little plastic card!
You tell me a vacation on this old earth that you don't pay inflated prices?! Actually, the drinks are the same price or lower than a lot of bars charge!
I guess there is only one solution for you-either quit complaining & go with the flow, baby or stop going!
