Tipping is not a must, but is appreciated
If you are happy with the service and the meal, you can leave a tip in Bulgaria. In Bulgaria, the service is not calculated individually. So, if you like your dinner, leave a tip, but it is not required.
After receiving the change, it is common tradition in Bulgaria to simply leave the tip on the table. Also, if you are not expecting change back, it is usual to leave the cash for the bill, including the tip, on the table and leave the establishment.
In Bulgaria, there is no hard and fast regulation about tipping, but workers will appreciate any tip you leave, especially in tourist areas, towns, and cities. Bulgarian wages are low in comparison to those in neighboring countries, and workers frequently rely on gratuities to supplement their pay at the end of the month.
If you're visiting Bourgas or Varna in particular, you'll notice that tipping is becoming more common. Tips are highly valued, especially in pubs and restaurants, where the standard tipping sum is 10% of the bill. If you believe your service was of high quality, a small increase (15%) would be greatly appreciated. This is definitely one of the top Things to Know Before Traveling to Bulgaria.
