Hey, been awhile- but I know where the answers are! :)

Someone has asked me which episode that Gomer explained, "...water and air are free but we have to charge for the gas..." and went on to explain that it depended on how many times the pump (or bell) goes ding-ding and then said it was xx cents a ding.

now... I think it was on "Man in a hurry" and 30 cents a ding.

But I'm not sure and canNOT find that episode.

Anyone?

THANKS (in advance)!

Oh well... I thought someone here could answer it- someone else has though (thankfully).
FYI:

It was "The great filling station robbery" and 30 cents a ding.
