There is one of these overpriced (and poor quality) stores right next to my wash. They do a killer business somehow, and, you guessed it, many of their customers park on my lot and go for their coffee. They seem surprised when I ask them to move and not do it again. Would sure love a way to REALLY discourage them while staying legal. Police said because this is a private business they can't do anything. Tried calling a tow truck twice but the idiots are gone by the time a truck comes. Don't want to turn into a grumpy old man but getting tired of them blocking my business. Thoughts so far are boots, spray paint, cordless drill to adjust the air in tires, and bear repellent.
