Re: One of my earliest hacks ...
My sister was plagued with calls for a local, quite upmarket, restaurant after an ad appeared in the paper with the wrong number. For the first week she politely told them it was a wrong number and gave them the correct one having informed the restaurant of the mistake. When the same ad went in, with the same mistake the following week she merrily took bookings for tables for 10, all vegans etc. The number was corrected in the following week’s ad.
