Only in Portugal will a business refuse your foreign card and only accept MBWay or Portuguese cards

Cash-only businesses, fine, that's a choice. But how about the ones that only take MBWay or local Portuguese cards and refuse anything else?

Are you actually doing the math, business owner? The 1% fee you might be saving is absolutely dwarfed by the volume of business you're leaving on the table from foreigners, tourists, and anyone with a non-PT card.

This is particularly absurd at places like 5àSec. You're the largest dry cleaners in Lisbon and you operate like a small corner bakery. Why?

Just accept normal cards like every other developed country.
