Minor annoyances at work
There are two things which happen at work which annoy me disproportionately:
1) People taking the elevator for one floor. I always take the elevator in the mornings from the basement to the sixth floor, and in the evenings I make the reverse trip. I'm always astounded by the number of people who will hop on the elevator to go up or down just one floor. I frequently have to go down to the 5th floor, and I always use the stairs. What's the point of taking the elevator?
2) People who don't run for the bus. If the bus is sitting there, and you're late (I can understand not making an effort if you know the bus isn't going to leave yet), then it's more than a little inconsiderate to nonchalantly stroll to the bus and expect everyone to wait for you. Show some hustle!
Yes, I know that not everyone at the Lab is in as good physical condition as me (not to say that I'm in great condition, but at least I'm young and healthy). But these are perpetrated by all sorts of people.
