I may be completely in the wrong here as I haven't been on holiday to a place with sun loungers since about 2001.
I was just reading reviews of places on tripadvisor (daydreaming) and noticed the biggest complaint seems to be people reserving loungers (with towels) and not using them. Some people said they were sat on grass next to unused loungers from 10am untilthey left at 5pm.
I would have chucked they towels to one side as 'abandoned' and taken the loungers by 11:30 latest.
When I went to Alcudia many many years ago each morning that we got up early for an excursion or whatever we could see the caretaker going around removing towels from loungers and dumping them all in one big pile, I thought it was genius.
AIBU to think people only reserve loungers with towels because other people just let them and don't speak up fecking remove the towels
