At the end of the day, if you know the restaurant is so busy and table seating is a huge problem...
... why not make plans with a backup restaurant in mind if you're meeting up with friends, just in case it's full already like it often is?
What if every other table was already occupied by people meeting friends. They're all entitled to be there. This lady only bullied OP and told him to hurry up because he was there alone. And what you're saying is that if you're alone, you're not really entitled to use shared resources beyond the absolute minimum necessary?
You're calling for mutual understanding while supporting the position of someone who demonstrably has none as she goes around ordering people to leave public spaces becauss they think they're more important. 'Mutual understanding' is revoked when it's clear the other party only wants to abuse it.
yes. it is not everyone else's responsibility to reshape reality to accommodate me. if the restaurant I'm meeting a friend at is full when we both get there, and it looks like the wait will be too long for us, we go to a backup location. sometimes that happens. it's life. at no point do we assume a position of superiority and arrogance and start accosting already-seated patrons issuing orders to vacate to make room for us. that would make me and my friends pieces of shit.
