This! Something is really off.
And I honestly would call licensing as well. Not sure that you could do a formal complaint because there is no evidence of any wrong doing but I would at least discuss with them that you are being given grief about picking up early. What would she do if you just showed up early? Because I would be tempted to do just that on numerous occassions to see what's going on.
