Sometimes I have to drive by car after going to a bar. Hence at these times I don't want to drink alcohol (even though driving after drinking a modest amount of alcohol is allowed where I live, I don't want to drink any alcohol at these occasions). However, I like non-alcoholic beer. From taste I cannot always tell the difference between non-alcoholic and alcoholic beer.
Hence, particularly if it's a busy night, the orders might get mixed up and I might get an alcoholic beer by mistake. Basically I see two options:
Making it clear at the order that it is important to me that the beer is non-alcoholic.
Or, when I get the beer, asking whether it is really non-alcoholic. Both could be taken as criticism, e.g. because I am doubting their ability to remember my order. Also, they might not want to admit if there has been a mistake.
So my question is:
How to make sure to get a non-alcoholic beer in a bar? Bonus points: It should not sound like criticism about the service.
