What makes someone cheap???
If someone goes to a nice restaurant, such as PFChang, and has dinner that would have cost $100 for 4 people and doesnt have to pay for it and just leaves a $5 tip. Now, does this classify someone as a cheap person??? I dont know about you, but I've worked in a restaurant and I've been served in a restaurant. I thought its standard to tip 15% and 20% if the service is good. Now, if you have a coupon of some sort, you should give them at least the 15% including the item deducted off the bill. Thats just me.
