I once went into a popular high street outdoor shop in Aberdeen and asked for a bulldog (which was hanging on the wall behind the counter), the shop assistant looked and me, gave a chuckle and said "sorry did you say a bulldog?", I smiled and said that was indeed what I had asked for, he then looked at me as if I had escaped from the local psychiatric hospital and politely informed me they weren't a pet shop. Thankfully one of his colleagues (who was actually a climber) had overheard our conversation and came to help before either of us got exasperated!
