Oh no that sounds horribly petty! Not to mention that it was the manager’s mistake, albeit an understandable one, since she didn’t know who you were at first.
The manager having a grudge over that would imply that your wife is somehow responsible for her mgr’s actions, which is absurd.
I will say that I love the checkout clerks at Sprouts. They are always so nice to me, even though I don’t always have my act together and have to ask questions usually.
