To tip or not to tip, and other questions about subsidizing the service industry

Tipping at a restaurant. Rounding up at the grocery store for a charitable donation. Using the self-checkout line without getting a break on the final bill. The more you think about it, the more you realize just how much consumers are asked to subsidize certain parts of the service industry. Is this ok? What are we actually getting in return? Temple University Associate Professor of Travel and Tourism Dr. Benjamin Altschuler examines these questions, and discusses whether traditional expectations in the service industry are overdue for a change.
