Surely more than 85% of places? My Amex is more accepted that that here in the UK, other than very small shops (Who these days still often accept it) and shoe shops (For some reason I don't think any shoe shop in the UK takes Amex). Even most of the local councils take it for council tax these days. For most bills Amex is not really accepted, but neither is MasterCard or Visa credit cards. You generally have to pay by debit card or by direct debit (A bit like an autopay bank transfer that comes out of your account automatically).
I live in the US for about 6 months every year and a half for work and I've never once had it declined but then to be fair I'm normally in NYC and since my employer pays for pretty much everything I don't go to many cheap places haha. I do remember one or two restaurants that only took Amex though!
For the OP though, unless your travelling outside of the US, Canada, The UK or Australia I don't imagine you'll have any major problems. Just use your debit card or other credit card on the odd occasion its not accepted.
