One of my colleagues was amused and bemused by this warning sticker inside the shower stall of her hotel room during a vacation to Norway:
Warning.
The bathtub can be slippery. Anti-slip mats are available at our housekeeper.
Please dial 7000.
Hmm, if the bathtubs are slippery, shouldn’t they already have mats in them? And isn’t it a bit too late to be dialing up the housekeeper for a mat once you’re already in the bath?
