This pigs me off every day.
So many businesses have at the entrance:
A set of two doors symmetrical left and right and forwards/backwards, both have pull handles either side, one of the two doors will invariably be locked (Why?) and the other has a 50/50 chance that you can't actually pull the door, you can only push it or the opposite, you can push it but not pull it. FML.
So you end up needing both hands and the quickest method is to pull one door whilst pushing the other door and if that doesn't work then you reverse what each hand just did.
Fucking shiity design everywhere because some lazy idiot architect can't pick a functional fucking door and because some idiot manager hasn't told the lazy staff that they should be unlocking both doors not just one.
Irony: the architects offices having these same bad doors.
