Cheap people

I learnt two cheap guys recently:

1. A master classmate
- an ex-colleague
- he joined our group project once and then sticked to us forever
- relied on others to get marks
- no contribution in group assignment
- pretended to be knowledgeable
- disturbed others during lectures
- could not follow lecturer's progress and asked about fundamental things while lecturer was teaching new stuff
- very thick skin
- even asked me to help look at his own assignment (and I found that he has not given a thought to the assignment at all)

2. A new colleague
- thought I was the secretary / admin staff when he came for interviews
- pretended to be gentlemen, but actually was a salty-pig hand
- always touched on females' shoulders unnecessarily
- not capable in doing his work and asked irrelevant people how to do his work

I don't know why there are so many cheap people these days! Let me learn how to deal with them. If I succeed, I think my people skills will improve much!
