fucking with people

so basically, whenever i'm at the airport, the ignorant passport stamping grunts who work there continually act patronising because they think i'm a boat person who can't speak english. (by the way, i'm a born and bred local - i just -look- ethnic)
what should i say to them next time they yell "YOU. HAD. GOOD. TRIP??  ENJOY.. HOLIDAY??"

just go

"mosa zippy sharmoot" = suck my dick whore in arabic
