One of the best jobs I've ever had was a trolley collector. It was a company contracted to work for the chain stores, so I didn't work for the stores I collected carts for.
I'd show up, do about 45 minutes of exercise hauling the carts around, then I'd sit in my car and play on my phone or read a book. Or, hell, even just leave. I'd have 6 hour shifts but trust me when I say the trolleys don't need 6 hours of supervision. I'd often get away with one collection in the morning, coming back for a collection in the afternoon, then peace out.
Anyway, best of luck with your new job comrade, I hope the freedom makes the lack of decent pay worthwhile. It definitely did for me.
