Drop back by with some honey as a goodwill gesture and to let him know you're serious if you really want the location. However, understand this may be a very difficult person to deal with. He's shown his personality. Any disagreements or difficulties he experiences with "bees" (any stinging insect) could create challenges that aren't worth the headache of putting, or having to retrieve those bees on/off that property.
I've been in sales long enough to understand that this type of person can be so hard to deal with at times that I'll walk away from the sale if I my "spider senses" start tingling. I'll let my competition have the headache. It'll drain more from them in time, headaches, and resourses than the profit added.
