I remember trying to sit at a table for two in a restaurant but a man sitting in the seat backing mine had pushed it right back so that he could spread his legs and I couldn’t pull my seat out so I politely asked him if he could move forwards, which he did, a few meagre centimetres, so we had to dine elsewhere, that table being the only one on offer, but not before I told members of staff why we were leaving and warning them that they might have to negotiate with the uncooperative man if another couple came in. And just for the record was plenty of space for even the biggest diner to sit comfortably. That was a few moons ago I doubt I would be so quick to walk away now.
