I doubt I am the only one who has experienced this one. Earlier today a new client. Booking was fine in my opinion and unless he was acting he really enjoyed it all too!
My complaint? I opened the front door and he came in with phone in hand. Hardly looked at me and walked past me while doing something on the mobile. Turns out he was switching it off which was ok by me but he barely glanced at me while walking down the hall, which he should not have done as he had no idea where he was going.
It pisses me off on the rare times it happens. If we sps did the same and kept our eyes on our phones while ushering them in we would be branded rude.
I had one man walk straight past me and say wow you look hot! the thing was, he had not even looked at me. 
I had an OC who pissed me off to no end. Keycarded elevator so he had to met me in the lobby of course. I'm sitting there, NOT on my phone bc I think that looks terrible, he comes up about 10 feet away from me & says, "Celeste?" I smile & say hello.
He literally jerks his head in the direction of the elevators & strides off to them.
No hello, no handshake, no greeting....not a fucking thing.
So I sat there. I thought, you know, that's really GD rude & I'm not letting you get away with it. You need to come back & acknowledge my existence, you rude bastard. About 30 seconds later he comes back with this surprised look on his face, & says, "Are you coming?"
"Once you greet me properly & say hello I am." was my chilly reply.
I sat there til he came over. I held my hand out until he shook it. Only then did I rise to my feet & sloooowly walked to the lift. THEN, we had to wait for that GD elevator to go up bc ppl from his conference (that he didn't know, mind you) were IN IT & he "thought it might be awkward."
I'm thinking, gee, I have *regular ppl* as friends, who says you're not meeting someone from, I dunno, your college years or something. Such guilt *tsks* & so unnecessary.
We're not even at his door yet & I'm fed up. As we're walking down the hallway I said thoughtfully, "There's several ways this could've been handled, you know. You could've left a key card at the front desk for me. You also could've come to me & saved yourself an awful lot of stress, it seems like."
"Uhhhh. I didn't think of those."
Clearly🙄.
