Then you are tipping too little. A normal tip is considered to be 15% so you need to shell out a measly 3% more.
Most don’t cover alcoholic beverages.
So whether or not you are going to use the certificates, you are going to drink anyways.
Sometimes you end up spending more than you normally would because you need to spend the minimum before the certificate has any value.
Unless you are dining at Micky Ds, it isn't hard for a dinner for two to hit $35.
Bottom line is that you save a LOT when using the certificates compared to not using them plus I NEVER pay full price for them when they are easily available for 80% discount.
Please add me to your ping list.
