We suggested to the man and two kids about including some vegetarian options. 

The boy was very polite and thankful for the input, as was the girl. 

There was a female member of public purchasing sausage sandwich.

We turned and began to walk off when the man passed some comment, interjected the female purchaser. Then we heard laughing and more words behind us.

This is a disgusting demonstration of ignorance.

In future if someone takes the time to give you input, about your money making sizzle; even if not to your liking.

Don’t laugh behind the persons back.

Very rude.

In addition, I hope other sausage sizzle operators give consideration to the vegetarians who are in the community, and incorporate some offerings so all community members can partake of your fund raising events.
