Anything you have on you. Most probably a key. Hook it on a corner and either drag it into a different position or push it up against the side.

Also, you can grab the attention of a worker. Or call the helpline.

Yes this problem shouldn't exist in the first place, but you have to be able to think to generally just survive.

Attempting to solve a problem by repeating the exact same action and expecting a different result is literally the definition of insanity.

After a recent "team building" work event, I'm starting to see how common this "well if this one thing that was my very first thought doesn't work then I don't know how this is ever possible to solve" attitude is all too common. It's just ridiculous and wastes time. (Not generational, people of all ages can be lazy in the aspect of thought. And it's truly frustrating)
