AITA for eating my friend’s doggy bag after he requested it?

Yesterday I was walking my broke ass (important for context) to the canna store to get some herbs, when I spotted an old friend who lives at the same complex a few doors away from me. Lets call him Flex. He was with his two other friends whom I’ve never met before. Our eyes met and he called me over, introducing me to his company as I set down. We started vibing and the conversation started to flow. As their pizza orders arrived, I quickly answered a call from a friend which took longer than anticipated, but she managed to send me some funds to get some wine. I quickly ran to the liquor store, bought the wine, left it at home, bought the herb and rejoined the group in under 15 mins. (for context, again, everything is in walking proximity and also close to were I stay so it is easy for me to get around)

I come back and offer everyone herbs but they had bought mushrooms and split among the group. They do not offer me any. They continue drinking before suggesting that we move to the next location. They seemed like a chilled vibe and there wasn’t much going on for a Sunday, plus I was happy that I was smoking, so I joined them en route to another chilled hippie joint. Before we got there, however, the friend says she cant walk around with a doggie back on hand, to which I suggest she put it in my bag so that it is easier to carry around. She agrees and we leave for the second location. They decide not to stay, and ask me to navigate them to a liquor store so they can get beers to chill indoors at Flex’s apartment. To this I agree.

At the liquor store they get just enough beers for themselves, and head towards Flex’s place. I quickly dash to my place, leave my bag and get the bottle of wine to join them. We chat and chill for a bit while we drink, before Flex asks to get some of my wine. I agree because 1. Flex and i drink together, and I had met him and another friend with a twin pinotage the day before. 2. I’m of the school of thought that if we chill together, we can drink together. Flex finishes my wine and drink’s the beers, and I leave for another engagement I had been keen to attend that went far into the evening.

When I get back around midnight, nice and tipsy, I get a message from flex. It reads "my friend left the doggy bag. Please bring it tomorrow I shall have it". At that moment I had completely forgotten about the pizza, and happy for the reminder because I was famished and considered that it saved me from the turmoils of cooking while inhebriated. So I ate the few slices left, put on some netflix and slept. I wake up and Flex messaging my inbox waiting for me to deliver the doggy bag. AITA for eating my friend’s doggy bag after he requested it?
