re: Tried to go to Mason's.........

That service is inexcusable. Mason's is definitely not a chain run by a policies & procedures manual, sometimes that is a benefit, sometimes it is a real detriment.

I have only written to restaurant owners about service issues twice, one called me with an apology and invited me back as his guest, that place is still going strong 20 years later (Mansur's). The other got defensive and argued how busy they were (for a half hour I could not find anyone to pay my bill to, so we walked out and I mailed him a check with the letter) they were only half full. He didn't last a year.

I'd be curious enough to write a note and see what happens, but that's just me.
