conversations with traffic wardens

me: is it ok if I leave my car there for 5 minutes?
traffic warden: ugh
me: I'm sorry?
traffic warden: ugh
me: so is that ok or not?
traffic warden: ugh
me: could you just use more words, I don't mind if it's yes or no, just more words would help ...or some words at least....
traffic warden: ugh
me: ok I guess I'll move it then..
traffic warden: ugh
