It can frustrating as fuck dealing with the public in retail. This kinda work can turn you into a misanthropic cunt if you let it.
What sort of stuff did you do to lighten up the day?
Me, my bro and Revol taking out of date food to the top of the building fire-escape and throwing at an adjacent building. Once a carton of yoghurt streaked all the way down the window and they didn't clean it for at least a week.
Taking out of date stuff and just smashing it against the wall out back was always good.
Dropping a water melon from the 7th floor fire escape
Spraying each other with the fire extinguisher (a bit anti-social in case there actually was a fire, but funny as fuck)
Serving customers in foreign accents - seriosuly try this one. You will almost certainly burst out laughing the first couple of times but it's worth it, especially if you are all doing it. I tried french, scottish, belfast spide, camp, they all provide a chuckle.
Adding random inappropriate words into customer dialogue - like made-up words for pound or change
e.g. instead of "27p change", "27p scratch", instead of "2 pound please", "2 scoops please"
seriously, if there's a bunch of you on checkout it's funny
Throwing food around the shop
Putting Morbid Angel on the store tape
Hiding behind shelving and shouting as loud as you can - brilliant, especially if a colleague is standing nmearby and gets the dirty look of a customer
If there's music playing, sing along as loud as you can, preferbly in a deliberately annoying way
Mashing the keys on your workmates till when they turn their back, so they charge the customer £764635732 for a tin of coke and packet of cheese n onion.
Any more?
when i used to work in argos we'd draw darts boards on the flat packed furniture and play darts with the little blue pens. and also see how long/how many said pens would stay hanging from the ceiling tiles before the boss noticed. we also once had a massive pen throwing fight, which nearly ended in tears when i got one stuck in a guys head from 30 feet. workers' solidarity
as you may have noticed, those pens featured heavily in our skiving activities.
