Yesterday. Sent older DS into his swimming lesson then took toddler DS into the waiting area with tables and chairs where families can watch lessons through window. Hardly anyone buys food or drinks (though you can buy snacks and coffees), many do homework, eat packed lunches, entertain youngsters with magazines or whatever. All very informal and people often share tables. There's an empty table with 3 chairs around it, one chair empty, two chairs with bags on. Nothing on table. No people at it. No other free chairs anywhere in the room.
So I sit on the empty chair with DS perched on my lap, slightly turned away from the table and consciously not putting anything on the table as I didn't need to and didn't know who had obviously 'reserved' the spot (though you can't reserve it really and it's not a cafe in that sense).
Moments later a woman comes up and says in an irritated voice, 'sorry I reserved this table'. I say 'that's OK I'm not using the table, I just need one chair (indicating DS sat on my lap) unless you need it'. She huffs and says 'but my daughter needs to do her homework'.
So I get up and say 'OK, I'll go somewhere else then', move away, stand there watching while she and her DD sit down and start homework, third chair still just has bag on it. So I go up to her and say 'Sorry, are you actually using that chair because if not I'd like to sit on it please' and take the chair away.
It just felt so entitled. If that had been me I would have said 'we need the table if that's OK but you can stay there', or possibly even just acknowledge that you can't reserve tables. I mean it's a shared space for people using the pool, not a homework club! AIBU or she a CF?
