Weirdos!

Saturday around 1pm my mother n law and I & my daughter had went to dollar tree. Everything was fine store was packed as normally. My mother n law is white and I’m black & so is my 4 year old. My daughter decided to walk with my mil and I was maybe 10 feet ahead of them. This guy maybe in his 60’s in the back of the store asked my mil “hey is this little girl lost, if so I’ll take her to find her mom”, I immediately turned around and asked him are you lost ? This is my daughter. He had this shocked look on his face and didn’t say one word. My mil had stated it was her granddaughter and we walked off. Idk what this guy intentions was but I’m still super pissed. I talked to a manager and they couldn’t find this weirdo anywhere.
