If they use a Groupon or restaurant gift certificate, diners fail to tip the whole amount. Tip according to the bill. Whether you paid full price or a discount, your server provided the same service.
However, a little additional courtesy can go a long way toward showing employees how much you appreciate them, especially if they're regulars at your favorite spots.
If you receive free drinks or desserts, add their estimated worth to your bill and tip accordingly. Even though they were free, the bartender or server went above and above to make your experience unique, so tip accordingly.
Add the approximate value of free drinks and desserts to your bill and tip.
Some diners worry about how much to tip, even though everyone knows they should. Experts have finally decided what's proper.
Tipping on the pre-tax amount is OK, but tipping on the total is better. If you're still tipping 15 percent at full-service sit-down restaurants, up it to 20 percent.
Don't subtract or lessen the tip to punish your service for uncontrollable circumstances during your meal.
According to other experts, waitstaff aren't the only ones serving you. The kitchen usually makes this error.
It's common to see a delivery fee on the bill breakdown, but it's usually a restaurant fee that doesn't go to the delivery person, so you'll need to tip the driver.
When your delivery arrives, be grateful if you stayed home due to terrible weather. Your driver should be compensated for braving the conditions you avoided.
