I don't understand why or how you'd lose ticket revenue? If you identified 20 passengers who've often bought tickets who are known drink buyers. Place them not together with random seat assignments. So they are by people unknown buyers and/or less frequent buyers No ticket sales should be effected. Only the placement of individuals. This obviously doesn't effect those who choose there seat. Buy late. Or buy for groups adjacent seats.
