I don't know if it's just cultural differences and they seem rude or don't know how to act... but these kids just seem ignorant.
I work with this Turkish girl who is EXTREMELY rude and lazy. She acts the same as you described with those brats. She sits on her bum all day and texts her boyfriend while I work. She lies to customers so she gets a sale, is rude to them and doesn't care, asks me uncomfortable questions just to get my goat (she just pisses me off), and, above all, she never apologizes or takes responsibility for her actions. I .....don't know how to say this, but she's not representing her generation, or Turkey very well. She's only been in America for four years. She is also only 18 years old. She's a spoiled little brat who doesn't deserve to get paid to sit on her *** and text her boyfriend. I'm sure not all Turkish people are like...her. But From what YOU say and my experiences, I would never go to Turkey.
Way to represent Natasha.
