I oversee a garden at an outdoor tourist attraction. Occasionally I invite other people to come with me. They get free admission, I get some extra help, and the organization may get some new volunteers or customers in the future.

If it rains, I have to reschedule. I am not sure how to handle it when the people I invite suggest alternative activities in the case of rain. I would prefer to simply not get together at all and to see the person on the day we reschedule. These are usually acquaintances I've met through a gardening program, not close friends.

I sometimes feel awkward about declining their suggestion that we meet for breakfast or coffee instead. Does that look really weird? It's not like I can say that I already have plans.
