Today I braved the hell that is commonly known as softplay. The weather was shit so it was inevitably packed.
All tables taken but lots of spare chairs, I asked about four different chairs only to be told they were taken - fair enough if they are.
So I was stood there like a lemon, balancing fruitshoots on the bubblegum machines whilst trying to read my game of thrones. (wifi was broken which added to my fury)
One woman I asked was sat alone at a table of 4 (but only 3 chairs were there iyswim) After she has told me the seats were taken she moved the two pairs of children's shoes off the floor and onto the table infront of the chairs. Another woman who I previously had asked (and if you're reading sorry if I was slightly blunt when you said they were taken 
) took pity on me standing like a lemon and brought over a chair but asked if her child could please use it when they had ordered lunch, I said no problem, we then laughed at how busy it was.
So I sat at space on the table for four and not once did anyone sit in the spare chairs, I was there for almost an hour when I gave the chair back to the poor kid wanting his lunch and at this time the other woman was getting up to leave. She actually said to me "we're going now, you can sit on one of these chairs if you want" 
I was too tired, in pain and generally feeling shitty to respond with anything other than a feeble "thank you"
So am I being unreasonable, saving chairs for children who are far to busy having fun and being little tearaways to actually sit on them is not on. Especially when busy and lots of adults have nowhere to sit.
