So, Casto doesn't want any food/coffee trucks to come by for fear of backlash from lessees (Like Champps or CoreLife or Barnes&Noble). Yes, a coffee van isnt much competition, but it opens up a can of worms with other groups wanting in, charities whining, etc...it can escalate out of control and get them - and the group, of course - in trouble.
I'd love to tell Tupelo Donuts and other coffee-trucks that they could show up but leave the parking lot by 10am, and I think that would work where none of the restaurants would feel competed against, but I don't want to be responsible for that level of effort/logistics/relationship maintenance with Casto.
