When you go to an Apple store with an Apple product that needs repairing and believe it will not take much time to fix your problem but end up being in the store for 2+ hours, when the point comes where you realise you were not prepared for this and have barely eaten all day and gradually start to feel malnourished.
Customer: Man this is taking longer than I thought! I only had a small breakfast
Apple Guy: Are you heading towards the path of Applerexia?
Customer: Yeah.. you should really have snack machines in these places..
