1. Key cards
We understand that they are safer and cost less if someone decided to take them back home, but do we have to be punished by them?
The ones that unlock the door only by waving are not that bad, but when we have to put and take it in for hundred times very slowly, and it still won’t open. We end up going back to the reception using the stairs because, obviously, the card will not work in the elevator now…etc.
Seriously, why all this torture? The suffering is doubled after a night of drinking, FYI!
