I had several similar situations flying around the world as an airline pilot. 
I always carry some (local) cash with me wherever I go. That said, in certain countries it’s more difficult that in other. Also, you end up with a whole bunch of useless paper if you travel as much as I do, considering that you often can’t spend it all and of the “I’ll  keep some for the next time I’m in town” mentality🤣
Once a year I’m at the money exchange to get euros or dollars back, usually loosing some in the exchange rate.
Nevertheless it’s always good to have some cash at hand wherever you go, until everyone accepts our sats over the lightning network! 

I’ll take the opportunity to thank Lyn for her always insightful and inspiring contributions, shukran.
