Neighbor Takes Advantage of Trusting Elderly Woman

DEAR ABBY: When dining out at an establishment where you order your food at the counter and then they bring your food to the table, is a tip necessary?

Also, when going to coffee shops, tip jars frequently sit on the counter. How obligated should I feel to tip the people behind the counter? -- JAMI IN NASHUA, N.H.

DEAR JAMI: Food servers often earn minimum wage, which they supplement with the tips they receive. If your server is efficient and pleasant, you should leave a tip. The usual amount is between 10 and 20 percent.

At a coffee shop where there is a tip jar, assuming that you did not sit down to be served, you should put your spare change into the jar.
