Courtesy of switching off others timer

Often time, in the lab, you will hear timer going off while the person setting the time is no where to be seen. Most colleagues will leave the timer sounding for exactly a min before the timer stops and resume count up (showing elapsed time).

If you are the unique group of people who can't stand the sound of beeps in the lab or anywhere, chances are you will go over to the bench and switch the timer off for that someone. The latter group of people, can be responsible or just not. The responsible ones will remind that someone about the time-up, while the irresponsible ones will pretend ignorance and wait for the someone to figure out.

Now, a common courtesy if you need to switch off someone's timed-up timer:

1. Switch off and start count up. The latter action is to remind the someone the elapsed time since time-up.
2. Remind the person if you see them about the time-up. 

See, that isn't to difficult to do, right? If you can't stand the beeping sound, do the right thing when you switch off someone's timer next time.
