It doesn't pay to be kind at times

I tend to have IT related jobs (higher tier) and recently have some marketing related ones, the only problem is when you call people, folks may think you are joking, etc. They view you with suspicion and even asked me how come i am not taking the role for myself as its a 6000 SGD job(to them its a lot). Its a bit frustrating sometimes when you want to help and people doubt you EVERY STEP of the way. Once they get that job though, suddenly disappear as if worried you want money or something.
