I agree with the 'get in/get out' idea. I'm not a waitress, and hate cleaning up after people. But, if someone can sit for a few minutes to enjoy their $5 cup of coffee (that cost me $1 to make), they might see something else to buy from the case or retail shelves.
Coffee is a huge profit center for a business. I personally hate coffee. It's gross. But I understand it's draw and money making abilities for my business.
WHAT??? I am afraid I can no longer be friends with someone who is such a polar opposite of me! It is too bad, because I thought we really got along well and had quite a bit in common ;-)
Actually, my MIL doesn't drink it, and we are great friends... I just finished a cup, and I am off to bed! I drink it all day, all year, hot or cold. It no longer affects me, I can fall asleep with a cup of it in my hand.
