I've come to a big soft play this morning, it's first day of half term (abroad) and out of 70 tables they are all taken. By taken i mean coats and bags draped over the chair. I can see one table of 4 with a coat on the chair and notebook on the table and 2 pairs of shoes so presumably 1 adult and 1 child. Would I be unreasonable to sit there (I'm 1 adult with 1 child) until asked to move? Lots of tables are "empty" as in noone sat there just belongings on them. Otherwise nowhere else to sit and I want to do some work.
