Newbie Tricks
When I worked for a theatre (entertainment venue, not a hospital), we used to send newbies to a local hardware store for some 'sparks for the grinder'. The store had the same sense of humour, so back came the newbie, asking 'blue or green?' We'd say 'blue', off they went, the store sent a message back with 'we only have green' - back and forth went the newbie! Other things: 'Ask for a long weight', "A short stand', 'Skyhooks' , 'Tartan Paint' and a 'bubble for the spirit level' - This is now irrelevant since Stanley now manufacture replacement parts for their levels and Skyhooks are now a brand.
