There's a difference in the feel of seal drag and normal (correct) preload. It's possible you're feeling the effects of seal drag which goes away as the seals wear and some grease bleeds under them, or it could be excessive preload.
If I had it in my hands I'd venture an opinion, but without actually feeling the drag I can't. Either the shop is right, and it's fine, or the mechanic is too lazy to check/correct what he sees as a minor (not on his bike) problem. One thing you might do is ask him to let you feel another bike with the same or a similar BB, and compare them.
