Agree 100%. Charging for tap water in Aruba would be a total turn off to me and I would not return to that establishment. We did not experience an up charge at all for using credit cards at dinner anywhere in Aruba. There are a few places at home that charge a small percentage - one bar/restaurant and my eyebrow place. I just pay cash at that salon. But we use credit cards for everything so it is very annoying to be charged extra for using them. I understand businesses are charged a percentage but in this economy they should be happy to host you minus the charge!
