I've only worked twice and not much happened in either place.
All I can really contribute is a "secret" I learned when I was doing telesales. I sold timeshare for a resort and we would give the option of getting to choose a free gift out of a selection of five if they booked with us on that day. The options were like one free ticket to go skydiving, twenty rounds of golf, two dinning passes etc. Anyway, we would tell the customer that they can only choose one but if the customer wanted more than one or wanted more than one pass then the sales person would typically give in. You can pretty much get anything you want outta them. The reason being that we are paid BIG TIME when we get bookings and if the only thing stopping us is one little gift then you're damn right we're gonna give it to you.
tl;dr if you're ever gonna invest in timeshare make sure you milk everything you can outta your seller.
I currently work at a library but nothing out of the ordinary goes on there.
