So, like, can you help me pump up my tyres, baby?

Good enough for me - I'm in!

Oh dear, you seem to have a problem with your bike. I couldn't presume to be so patronising as to assume you don't know how to use a spanner yourself so please feel free to climb into the back of my van and help yourself to any tools you like. They're all in that box, right next to the mattress................

Add something along the lines of... 'Say, are you about a size 12?' then slam the door. You'll be laughing for weeks with your small dog called Precious.
