FRONT DESK CALLING FOR NO REASON

I checked in to a hotel for 4 nights . Before checking in I had to call the lady at front desk to let her know I’ll be arriving late on the first day , so she went ahead and charged my card and held the room for me . I gave her my credit card and she told me the amount . She told me it was $300 in a awkward way in which I already knew the price. Check out time is at 12:00pm

On the day of check out I called the front desk from the room at 11:45am to make sure the check was at 12:00pm and not 11am , the lady answered the phone and verified it was at 12pm . Right at 12:02 pm I was packing my bag and Almost out the room , the same front desk lady called and said it’s past 12 I said I’m almost out the room now . And she asked when exactly would I be out the room because they will charge me another night if I’m not out by 1:00pm . I told her a few minutes and she said it’ll be fine in a passive aggressive way. I think she was just picking at me because housekeeping hadn’t even come to the room for cleaning yet or anything , I didn’t have intentions of I guess just staying on their property without paying them . Everything I did was innocent . During my 4 day stay I bothered no one , guest nor front desk .
