Hey hon, girls will be girls!
Love chatting, hey it's fun :-) makes a boring job pass more easily, etc.
My advice, do not show too much 'attitude' lest they'd get mean.
As for you face --- SO WHAT?!
They'd be rather jealous not to have had that 'face lift, nose job, etc.' you had. So be kind to them, play it down and don't - I say it again, get into 'attitude'. Women like that HATE what they'd call 'snobbish' behaviour.
Just have a good story why you wanted it --- to please your boy friend, lover, what ever be a good one. Most boob jobs are initiated by male partners in my experience. We all want to look our best, it's in our DNA :-)
That's my 2 cents,
