Go round, look them in the eye and ask for it politely! If they don't oblige(sp) then take a step forward, and ask again! If they still say No, then you get yourself inside, however that may be!

Don't take shit lying down mate, or others will do the same, you come across as a sound lad on here, so just make yourself confident enuf to go round nd get whats rightfully yours!

All the Best bro!
