for those intending to work in this job for the sake of $$$,  and shoving away all the RISK AND DIGNITY in hand, its very hard NOT to judge them in "certain ways", right?

We judge a person by his/her action and intention. These intention will soon translate into the things they DO, that includes JOB and CAREER. So "nobody has the right to question nobody's job" is subjective. We can question it especially when its brought up in a forum NOT by the questioner , but by others who wish to discuss about it.So get ready for bouqets , AND brickbats too.
The problem is not just about the job. It might be a simple "beer serving" tasks. The problem is with the IMMINENT RISK there. Don't simply push aside and said " oh I'll take K of myself. I won't let them touch me. I will know how to handle 'em bla bla bla..." . 

Remember, such a job puts ONESELF  in the presence of  MANY MEN . How far can that one girl protects herself. If these people wanna gang up and take advantage of you, there is NO TURNING BACK, especially they are further intoxicated by alcohol.

girls, the price of your dignity is worth how many litres of beer? =)
