Prices Subject to Change....According to customer's ATTITUDE
I saw this sign in a pizzeria and it made me giggle. Though I can’t actually hang one in my restaurant—though I wish I could—I can confirm the sentiment to be true.
Quick tip: If you are pleasant and don't complain I am much more likely to "forget" to charge for that soda on your tab. If you are extra friendly I might throw in a freebie with your take-out order. That said, don’t worry if you’re a jerk. I will never overcharge, but please don’t expect any freebies. And I will absolutely remember to charge you for that extra side of ranch dressing :)
