Perhaps I have been disproportionately annoyed by this phenomen burn i consider it rude when people misuse their ChaiR/stool at a restaurant bar to sit sideways. Bar seating is specifically measured and configured with the idea that patrons will sit forward in their seats. The space between chairs is limited and communal in the sense that if I get out of my chair, then I will occupy the entire space, briefly. People seem to think that if they turn their ChaiR to the side, or their entire body to the side, as chairs with backs do allow this, then they are taking up. O more space than they would if using the ChaiR properly. If the restaurant/bar isn't crowded, of course it is a non issue. When nearly every seat is occupied, it creates line seats that almost can't be used while still preserving the designated spacing. I hope explaine this well. I'm just mysteries by people who think having their body in the space between chairs does not affect others like a domino affect or worse if you are next to one them.
I don't ever say anything though I may use wordless communication with the bartender so that she may ask others to shift, if absolutely necessary. But shouldn't folks have more awareness of when their body takes up more than its allotted share? There are many variations of this issue, including when people treat bar seating as flexible spreading out their chairs, etc. Again, a nonissue when the space would go unoccupied but that's rarely the case in NY. I also have no issue, if someone is misusing a ChaiR, for example with their purse, and it's the last seat but when she sees me or I ask if it is taken, they immediately remove it.
