[FM] Tinder Date was Accidentally a Grandpa LoL

Soo I was swiping on Tinder like always and sometimes I just swipe without watching (haha) and then I had a Match with one older guy (I am into Older guys btw.) He looked like about 45 Years maybe.
So he Texted me and messaged back , the convo was pretty fluent and easy. On the same they we matched he asked me to go out with him , I was bored and gave it a try , because usually I dont date directly. So I came by bus to the city centre and he probably by car I am not sure and then I was standing there and messaged him i arrived.
There were a few people and one man was coming in my direction with a walking stick, slow speed , hat, glasses , cigar in mouth and a phone in the other hand.
I just didnt realized its him and then when he came up to me I thought he wants me to help him over the street but he showed his Tinder on his phone and it was him.
He didnt tell me that the picture was old and that he is over 70 years.
But it was just 2pm , he apologized and I went with him drinking a coffee , giving him a nice time because I know that old men loves to be around young girls , so i decided just to make him a nice day :)
After the coffee i drove home and deleted him then haha but he has nice memories now

Did I react correctly or should I blame him for the from information?
