I worked at kwiksave back in 1999 and it was a shit hole then too, I had just left school and it was a case of walking in off the street and asking for a job. the next day I was getting till trained, and was stocking shelves.
I have no idea what I was doing, but I think all the staff there felt the same. nobody cared and the customers didn't care either.
I lasted a whole month before walking out and working for burgeoning, and that wasn't the best job ever, but the staff there were full of fun.
