There are many synonyms that can be used to describe poor tips. Some of these synonyms include skimpy, stingy, paltry, meager, and inadequate. Other possible synonyms include miserly, cheap, tight, and insufficient. Regardless of the specific synonym used, the underlying meaning remains the same - that the tips being received are not adequate or satisfactory. This can be frustrating for waitstaff who rely heavily on tips to supplement their income. It can also be disappointing for customers who may not realize how important it is to tip appropriately. To avoid such situations, it's always a good idea to be generous and tip well for good service.
