Let me empathize the question better: as in restaurants adding a surcharge imposed towards customers just because the logistics of bringing in the ingredients to cook dishes is being impacted (usually come in bulk from supply trucks) alongside the cost of fuel going up.

I know its the same thing for rideshare (as drivers need gas, so they charge passengers more on the app for this reason). In my country, they added a 5% surcharge for customers who dine in at restaurants and 10% for food deliveries, which is just ridiculous (but I get it).

I mean, my country has it's own oil reserves but whether they'll be used during this time remains unclear, and they're kind of seldom on exporting that towards the global market since for the most part, crude oil is imported from the Gulf states (like Oman or Kuwait).

I mean, even though USD is a popular currency: does the PPP hold up in Switzerland? The thing is that, despite having $10,000 (CHF 7905) in their budget, that still won't cut it since there is a bottle of liquor that costs CHF 100,000 ($126,755) for example.

Don't even mention restaurant prices, it's ridiculous that buying from the supermarket is cheaper. Have you been there? If so, is it even a wonderful country to visit despite how expensive it is for tourists? (Explains why barely anyone goes there).
