Brett prefers not to encourage gratuities for parties and corporate events
from your guests – but this is not written in stone. He will accept
gratuities at engagements if people insist, but typically he will not
encourage (nor expect) tips from guests at a typical corporate event or
private party. An exception at the end of an event he will accept
a gratuity from the host of the event or company if they were thrilled
with the performances and his work, but this is not expected by any means.
