Putting aside the fact here is no such thing as hot coffee anymore, why would anyone even want to try and juggle a cup of liquid when they are boarding a plane and trying to manage their carry on, while navigating the other pax stowing their bags in the confined space of an airplane aisle? This "compulsion" reminds me of all the mummy bloggers, celebrity models and "social influencers" etc etc who seemingly can't go anywhere or do anything without a coffee cup or water bottle in one hand and an iPhone in the other. Why is it so important to look so busy that you can't stop and drink a coffee like civilised people used to?
