So, a student gets all keen, books a holiday but is too feeble to take advantage of the club buying a bunch of new suits from a local manufacturer.
Eventually maths intervenes and the diver realised they need a suit real soon now. Divers goes to a shop and is sold a second hand suit for about £400 (by way of comparison - new the club paid £800 including an undersuit).
Of course it turns out the suit leaks. Certainly at the wrists and maybe elsewhere, the diver’s arms being wet to the shoulder. The diver is in denial to begin with, blaming it on failing* to understand who is responsible for the zip, fiddling with wrist seals and so forth. Eventually though it becomes clear that best way the wrists are too big, worst way it is a tea bag.
So, the diver takes it back to the shop. They say, “Yes, of course you can have your money back, but we will knock off £50/day rental for the time you had it.”
Clearly this is in contravention of consumer law. In these days of FB and social media it seems extremely short sighted too.
