I've never sat in a place for an hour and not been served a drink. The server brought water and asked what we'd like. Having just sat down, we'd said we needed a minute. She didn't come back to take that order. Another server worked on the tables around us, and eventually brought us more water, but also didn't ask what we'd like. It became a kind of comedic moment, like one where you wait for that guy from Just For Laughs to jump out and tell you the crappy service will live on forever on airplane entertainment terminals.
But it wasn't a prank! The original server came back an hour later. She was on break--possibly eating and drinking--can't be sure, as she only stood there as we explained that the window for ordering food and drinks closed ages ago. Weirdly, no actual apology.
More bizarre than anything.
Maybe wear fluorescent clothing if you go to ensure service.
