Our waitress figured out that I want my coffee refilled only once. Take your pick. At times, becoming a regular has been frightening. On one occasion, our waitress didn't bring us menus. We've learned about the disadvantages of being a regular.
Regulars have to leave bigger tips.
While few expectations are put on a guest, a regular is expected to be friendly even when not feeling friendly. Getting to know people is always a mixed blessing. We are glad to know that our waitress has children, but sad to hear when one is sick. Overall, this has been a good experience for us. Just recently, Carol and I decided we are genuine regulars.
