Any man who is beyond college age, and who sincerely does not realize the meaning of handing out gifts and asking women out to dinner, is an idiot and should be removed from any position of authority. Emphasis on "sincerely" -- Randy Komisar is not that stupid, and his denials are hardly sincere.
The line "his wife bought the gift for her" has become something of a cliche which married couples use when the husband has been caught flirting but the wife is not yet ready to end the marriage.
Gifts given in public, for work well done, are always welcome, but a pattern of private gifts and requests for dinner are universally understood to be requests to initiate a sexual relationship.
One last word about "sincerely" -- there are some men who sincerely are that stupid. I have known at least 2. They somehow reach middle age and it does not occur to them that the gifts they are giving to an attractive young woman are being interpreted as sexual overtures. As Schiller said, "Against stupidity, the gods themselves struggle in vain." There is no cure for such men, but they need to be kept out of positions of power.
