A floating fresh beverage
It seems pretty ungrateful to complain about something while inside a pool, given that many people don’t have access to one. However, pain is personal and cannot be compared. You could suffer because (from inside the pool) you can’t reach your beverages, for example.
You shouldn’t, though. With a Tupperware or a Ziploc, you could have the beverages in the pool. The water would even cool them. You will need to attach a container to a couple of woggles to make it float and voilà.
