I understand your frustration but I understand guard's majboori as well. As other people in the comments said, they work for 12h and are treated like shit by their supervisors. Most of them actually sleep outside the place they guard and most likely from villages just trying to provide for their family back home. 30k salary is way less than bare minimum. I know those fake smiles are very irritating but if they are not being rude, I would suggest giving them 100 (depends on your pocket) and specially the one who are too prideful or shy to ask.

Think of it this way, you are on the giving side of the situation, Allah ny apko is kabil kia hy so try to do this little act of kindness, not just because you are forced to, but from your own heart. That kindness will return, one way or another.

But what i don't support, are those beggars. don't give them a single penny. the guard is atleast doing a job, these beggars (Specially in johar town) are leeches to our society.
