Mrs Salad and I went to a pub yesterday that was obviously converted from an old cinema. Wonderful art deco interior (The Peter Cushing in Whitstable). As there is building work being done to the "foyer", everyone had to enter and leave via another exit, which was obviously the old fire exit down the side of the main building. Which prompted Mrs Salad to recall how her and her friends would regularly bunk into the Saturday morning pictures via the fire doors....
As regards getting into things without paying, I can't say that we have, but this Summer we will again be working as volunteer helpers at Broadstairs Folk Festival, which entitles you to free entry to all the concerts, shows and activities throughout the week, during the hours that you are not working. Great fun!
