Behold, common, everyday hotel laundry room equipment.
On the left, the humble dryer. On the right, the serviceable but modest washer.
Guess which one I happily loaded clothes into, added detergent to, dumped coins in, and then sat and watched for a good fifteen minutes before finally thinking “… wait a minute”.
Bingo.
(In my defense, I was very tired. Honest to God, this is not the sort of thing I do every day.)
