Is there a reason why lone diners do not deserve welcoming hospitality? No prompt greeting but a "I'll be with you in a minute", walk away and do other things to ignore you? Ready to order and she walks right by you with dirty dishes in her hand?

A better practice is to contact this business directly and voice your concerns and experiences, instead of being a troll.

Hey Debbie, sorry you had a poor experience. We are new owners that have taken over since you originally posted this. I just got an alert from Google that there was a discussion here. We have made a lot of changes! I hope you come give us a new chance!

Sounds like she was doing work, ever tried it?

Actually yes. Some looking at a single diner never think they will tip as to. This is not a unique experience, yet an indicative one.
