I would argue that this thread should be moved to the Dream Downtown thread.
Ultimately, it’s unclear if OP went in to these phone calls with an antagonizing attitude or not. If they asked for clarification or to see if it’s a mistake, okay, but if they went in with an attitude, then I can see how this didn’t go well. It’s also hard to judge as we don’t know the tone of the voice of the associate (New Yorkers aren’t known to be warm and fuzzy) when they told OP they could sit on the ground.
Regardless, this is a nightclub hotel with all of the various nonsense that comes with it.
OP’s Hyatt concierge shouldn’t have been rude as long as OP didn’t come in with unnecessary aggression or attitude. The concierge doesn’t have control over the chair policy.
