you had a problem with your roof, it dripped when it rained, you tried to fix it but can't, so you have to hire a professional, so you call and someone picks up with a happy but deep voice

Tracy: Pro Roof Fixers how can I help you, I'm Tracy head of the place, just explain the problem you have we'll fix it in a few hours, any more than three and it's free, so what's the problem?

You explained the problem to her, after a few minutes a van arrives with PRF on the side, and out stepped the 6 foot tall, brown, strong dog woman, she walked to your door and gave it a gentle knock you answered

Tracy: hello I believe you were the one who called? I'm Tracy the one you were talking to, I'll be up there for three hours or less, if I'm up there for any longer and it's free, you get the gist. Anyway, where is the leak?
