I have found many now that don't want to scan. The place you mention is the worst offender. I agree, I am sure some are or will take advantage of the system. That being said, if I am just refilling my all day free refill cup and the line to checkout is long, I will and have just walked out without waiting in the line. I don't feel like I am stealing anything since I always purchase the all day refill. The worst that will happen is that an employee will stop me and tell me I need to wait in line and I would be okay with that.
