I'll be visiting the US. I have several questions about money and card use in the US, the grand scheme is somewhat: What is my best strategy for paying stuff there?
- I suppose that I can pay larger amounts by credit (debit) card - for which amounts do I need cash in daily life, with how much cash should I run around?
- How trustworthy are people with cards? If I pay a waiter with card and he takes my debit card and goes to the counter, is that considered rude or normal? Is there sufficiently much abuse going on that it's not rude from me to want to always see my credit cards? Does this maybe only apply to certain places?
