Credit cards are accepted almost everywhere you go. But, what if you want to pick up some small purchases at a street fair? Or, what if you want to grab a cup of coffee from the local bar? Cash comes in handy. It's quick, easy, and often appreciated.
You don't have to carry a lot of cash. Just have some to use when necessary.
If you do want to use your credit card and you aren't sure if the vendor takes them, be sure to ask before you receive any kind of service or goods. Asking first saves everyone a lot of grief and embarrassment.
