It happened with me as well, yesterday i was in Body shop City centre, i bought some stuff and put on the counter, two local ladies were there, they came and put thier stuff on the counter and got angry with that fillipino cashier, because he screened my stuff first, then he said mam can i do first for them , and politely i said okay no probs, and then she looked at me , because i was smiling, see guys, all are not same, but if you are not qatari, and specilly if you are indian just bear with them, and be polite.,,,,show them your politness and show them you are good and civilized indian.
