I was trying to save one database trip for loading the User object (except the first time).

Why? Had you noticed a performance penalty with the extra database trip? Had your users complained? Were you 500'ing requests because your servers were overloaded?

If the answer to the above questions is no, then don't worry about performance. Performance is something that should be addressed if AND ONLY IF it becomes a problem.

Being right, does not endow the right to be rude; politeness costs nothing.
Being unknowing, is not the same as being stupid.
Expressing a contrary opinion, whether to the individual or the group, is more often a sign of deeper thought than of cantankerous belligerence.
Do not mistake your goals as the only goals; your opinion as the only opinion; your confidence as correctness. Saying you know better is not the same as explaining you know better.
