A few days later an older female bartender refused, saying she would be fired if she served free water, we left.
I can only imagine who the said bartender was, pretty sure I know.
Overall, we usually have pretty decent service everywhere we go. On the past trip there were two exceptions, both on the Dutch side. One is a very popular place at the end of the runway, and it did not surprise me since the 15% is added. The other was at a high-end, well established place with no 15% added and I was pretty shocked at 3 instances involving service, especially at this place.
