Actually I dont understand whats the big deal, usually people likes to waste their money in so many different ways (like making that kind of
sign) and beleive me, I think I have a magnet for people like that.
This case sounds like a joke to me and in case is not a joke youre just getting paid to do the job, if you dont take the job... somebody will and get the money.
I remember once I did a
sign that said something like "Give me my house back", I guess a divorce or something, dont care, printed 3 copies of it as requested.
