I walked in with a smile on my face ready for a good Mexican dinner. I was seated by a nice hostess, and there I sat for 15 minutes whilst a waiter and waitress served the tables around me - all the while ignoring me. Eventually I asked for service from one of them, and I was told that she would pass on the message. The restaurant was NOT that crowded, so it probably wouldn't have interrupted her schedule to at least take my beverage order.
And still I waited. Finally out of frustration as I walked back to the front door I mentioned to the person at the hostess station that I been there 20 minutes without a server - and I was greeted with a shrug of the shoulders like "why should I care?" Why indeed.
