What is convenient for you may not be convenient for someone else. Do remember that, the next time you are wondering why the lift is not working.
And read the signs.
Always read the signs.
I feel like that (the statement above) is a good motto to have in life. It lessens the (usually) unpleasant surprise element, while also making you look smart. And be smart. Of course, sometimes, the signs have been put there exactly for the super smart punts who think they are smarter than everybody else.
It is such a dog eat dog world out there.
It really is.
