Hello again.
I only noticed this minor bug in your current adventure while
debugging my own taverns.

If "Tip Barkeeper" is active the special code does not check for how
much gold you have if you either press OK without entering any gold
or if you type in '0' gold. You will get the thanks for your tip
message.

In my current adventure I jump back to the show menu screen if either
of these actions are initiated.

Regards,
Simon.
