We always take friends to this brewery because of the beer which is just good.
But this is definitely the last time. Bar staff thinks to be very funny after our friends (who are not Dutch) try to order 3 beers in Dutch which is not even necessary as they are tourists, because that was repeated they said ok you want 9 beers in such a sarcastic way that it wasn't even funny. My friend tried to give a hand "if it's a joke ok" even that hand was refused and then his beer too. They treated him as if he were drunk while they were not.
We both have been working in the hospitality industry for years and we have our own business, the way people treat customers is just rude and nothing more than that.
It was thought that this was "Amsterdam humor", and also ask where I come from, sorry but this humor is definitely not Amsterdam and just got rude !!!
We asked about the manager but he was not there or something.
The beer had a bitter aftertaste, but luckily it did not ruin our day and afterwards we enjoyed hospitality businesses that do provide service as it should ....
