Same in Europe. I have an Amex card from work. Hotels and most restaurants accept it, most taxis and shops don't. They absolutely hate that card and even if they accept it you practically have to beg them to take it (and even then they will pretend "the machine is broken"). Even in big countries. Try to get a taxi in the queue at Charles de Gaulle airport in Paris. They will ask you to stand on the side and beg each taxi driver until they finally get one for you.

Also the damn thing never works in machines, like for public transport tickets :( Which is often a far better option than taxis.

I have to use that card for business expenses and I hate it so much.
