I used to work at a Booker Cash & Carry. Now and again, staff would be 'asked' to help load cars and vans for customers. The thing with Bookers is that people didn't buy, say, a bottle of Coke—they bought several cases of the stuff. And so, you'd spend a half hour lifting a half-ton of crap into someone's van. Every now and again, someone would tip you a couple of quid, and, laughably, we were supposed to put this into a tips jar, so it would be shared equally. The reason: "It's not fair on the guys on tills and reception otherwise, because they have no opportunity to earn tips". No, but the sod on reception also got to sit on his arse all day, barking orders, rather than doing any work. Gnh.
