Q:  Our flotilla meets at a public dining facility. We have a meal there. Would the Tropical Blue Uniform be appropriate in that case (as opposed to the ODU for meetings that are not in a public place)?

A:  The uniform regulations describe Tropical Blue as the appropriate uniform for all situations where a coat and tie are not appropriate.  ODUs may be worn to a meal in transit while doing business.  In your scenario, you are conducting business at the meal (as opposed to "in-transit").  Hence the Office of Auxiliary believes Tropical Blue would be the appropriate uniform.
