Sessions can be long and boring so I get they want to play on their distraction toy.
Most people that play live know ppl are talking and doing other things than paying attention to the button or whats going on so whether its a phone or not shouldn't be a big issue.
If something like that bothered me then I would just get up and leave and go play video poker/
slots or go for a walk or look for a buffet or go talk to someone or go on a tour of the casion, lol, a trip to wash my hands or . . . or just bail on the session if something like that irked me because I knew I wasn't ready to play if something like that bothered me.
If I wasn't ready for that then the donk raising with the qj, t9s, 54s from early position, not knowing what they're were doing and hitting monster hands post flop was really going to upset me.
I would lose it if ppl on either side of me at a table were actively going back and forth having full blown conversations with me in between them. I'm wondering, why didn't they just move over one seat before I even sat down? I mean, lol.
But that's what you get online or live playing low stakes, people that don't know what they're doing, not paying attention to what's happening and they have whatever crazy idea of what poker is in their silly minds like showing up to a low buyin live table with sunglasses or having lots of aggression in their game without any knowledge of starting hands, position or just basic fundamentals of whatever form of poker they're playing.
