..when the service is outcall?
Just thought this ad was odd.

Same idea with those that post things like 100% guarantee.
Right. Lol. Not satisfied so I guess I get another hour for free. Sure!

That and "I do things others won't."

It's all marketing. Nothing more. Sure the outcall comeback for more is sort of an oxymoron but she's selling the "I'm that good' you'll want more.

I get a certain amount of daily entertainment perusing the BP ads. Some of the ads are so bad they are humorous.

If the posted picture is remotely accurate, the semantics can easily be worked out.  I guarantee it.
