My parents had five beers each and I had three orange juices and our bill was 400 PLN, do you believe that it was right?
You should have seen the prices before ordering. Without it, it's like signing a contract with the price to be filled out later.
Not asking about prices was common in Poland when I was there. It would be embarrassing to ask and refuse to buy because it was too much. We were lucky to find anything available in the stores.
Fast forward to the US where price is first and where there is no shame in saying that it's too much or 'no, thanks'.
Last week I made an exception and ordered a beer in a bar in North Utica - my favorite little town in Illinois I visit after a walk in the Starved Rock park. What kind of beer would you like? Cheap and cold. That will be 2 dollars. OK.
I learned this sequence after I paid 8 for a beer at South Beach in Miami without first asking what the price was. I can afford but I will not pay 8 for a bottle as a matter of principle.
