Kansas City is one of the US host cities for the World Cup this June & July. We have four teams basing here: England, Argentina, Algeria & the Netherlands. The projections are that we can expect >600,000 visitors during that time.
Restaurants are preparing their staffs to expect minimal or no tipping from foreign visitors. Some restaurants are planning to charge a fixed 18% service charge on bills to cover this.
This proves nothing other than how to deal with non-universal customs. I thought it might be of interest to see when the shoe is on the other foot.
PS at the same time, the municipalities are encouraging people to open their homes to short-term rentals, (loosening restrictions) and waving public drinking ordinances.
