Bill,
Believe it or not, they invited me! I didn’t even ask for their ‘mission statement’, I just gratefully accepted. lol. Hopefully, the post above is my one irrelevent, stupid post of the year.
 
On a more productive note, I have a packet with a picture of my cart, my name Tasty Dogs, my city and telephone number on the front. Inside I have copies of my state licence, resale license, city license, health department license and a copy of my insurance liability policy. I made up a number of these and hand them to anyone I’m trying to set up an event with. I think it let’s them know that I have a legitimate and professional business.
 
I have been thinking about my ‘mission statement’ and think I might have something.
