That is becoming more and more common and it's very grating. Young people hear "famous people" saying this and then start saying it themselves.
Once standing in the queue in Costa Coffee, two girls infront of me, possibly in their early twenties. The guy taking the orders asks them how they are and what could he get them today. The reply from one of the girls was "So, I would like a decaff, soya latte." The second girl says "So.... [long pause] I would like.... [another long pause] So I would like the same thanks".
