transaction fees – How exactly do El Salvador consumers make Bitcoin payments?

Bitcoin has become legal tender in El Salvador. It means that shops and businesses have to accept/allow it.

Ignoring the price swings, how exactly is this done on a technical/practical level? If the transaction fees are this insanely high, even for somebody living in an (alleged) “first world” country, how can anyone in El Salvador ever make any Bitcoin transaction except to move really huge amounts of money (to them) at once?

I’ve not heard one word about “Lightning Network” or anything in relation to El Salvador, and besides, I find LN to be impossibly complex and immature, so I cannot even use it myself, as a Bitcoin “expert”/”poweruser”.
