Yes man like everyone said it's totally cool.
My jobs the same at times with working to specific time slots for deliveries and getting through shit loads of orders while others aren't pulling the same damn weight.
Times I could choke a fuck wit to especially when ya know your doing twice the job they are.
Take whatever time you need man and if u need to chat or (not to sound patronising) someone to just sit and listen to you rant you know where to find me.
Take it easy man and twiddle your ears for a bit and say whooooo saaaaaa a few times like Martin lawerance outta bad boys 2.
Peace it out my man!
