All I’ve heard is that it’s hard graft ■■■■■■■ all the deliveries into pubs, restaurants, canteens or hotels etc in fact some places like you to put it away in their store cupboards/fridges sometimes up flights of stairs and can be quite a few drops too but maybe that’s why they pay a reasonable wage, I used to work with someone who did it for a while and he lost a couple of stone in the process.
