chicken salt 30c a sprinkle

I called into a fish and chip shop in Nerrandera yesterday and asked how much the minimum chips were; $2.I then said I would like $2 of chips with chicken salt and the lady said that will be $2.30c.I asked why the 30c surcharge for the chicken salt and her reply was ;" do you know how much chicken salt costs".
Anyway I just had $2 of chips with plain salt and the plain salt was free.

I dread to think how much the cost would of been if I had of asked for vinegar.
