Tipping at a Capital One lounge (like those in DFW, IAD, or DEN) is not expected or required, as the experience is designed to be all-inclusive for cardholders. The staff is paid a full wage rather than a "tipped" minimum wage. However, in American culture, it is common and appreciated to tip $1–$2 per drink at the bar if you receive great service, or perhaps a small amount for someone who goes above and beyond with table clearing or specific requests. There is no obligation, and many guests do not tip at all; however, if you find yourself at the full-service bar for multiple custom cocktails, a small cash tip is a kind gesture that is never out of place in a U.S. airport lounge.
