Scummy, is a bit harsh. I was just thinking of the look of bewilderment on the customers face when they got a totally random item.Wow, what a scummy thing to do.
I did supermarket delivery picking for a while, every so often the crates are randomly selected by the system for manager audit, not just of the individual pickers, but also of the drivers to make sure they're not sneaking extra stuff out of the store in customer crates. Sometimes a picker or driver that's already got a strike against them from a previous mistake might be getting every crate they touch audited without them knowing. So your antics of putting extra things into a crate could very easily get a picker or driver hauled up before a manager to explain. They might get a performance related pay hit, they might get sent for retraining, they might lose their job. Seriously the picking is incredibly regulated and monitored. Please stop messing with innocent people's jobs like that when you don't understand the extent of the auditing and scrutiny that goes on.
Also for another poster that said about the pickers hurtling round the store, it's because it's all timed, you're supposed to hit a particular pick rate, different stores take it more seriously than others. There's also timers on the chilled and frozen crates where they have to be completed within a certain precise time so that the contents of the crates aren't out of the cold chain too long. If you don't pick the whole chilled or frozen crate in time someone else has to get a new crate and finish it off and it flags up and is generally not good for picker <-> manager relations.
Consider me suitably chastised.
I nearly missed this post, as it didn't show up in my alerts. Unfortunately your overreaction made me laugh and I am sure that was not your intent.
Anyway, I won't do it again. Promise
On a side note, did you ever get into trouble for this. Methinks you did.
