AITAH for not boycotting as a Muslim ?

I really want to know AITAH for simply not agreeing with someone ? I’m a student who’s also Muslim , I recently went out with friends and we shopped for a few hours. Then another classmate who I’ve only briefly spoken to 3 times in 4 months joined us and we went to shop in Zara and berskha but we didn’t pick up anything because we didn’t really like anything at the time . Me and the classmate were smelling perfumes. We were looking for food places but the lines were very long as Saturdays are busy .Finally the classmate who had only been with us for 20 mins , took us on a 20 minute walk to another restaurant where she stated the options were limited and I may not enjoy .

I had spotted a McDonald’s and said I’m really craving one , I’ll get one on the way back if the food isn’t great . To which the classmate responds ‘ that’s really gross that you don’t boycott ‘ and I said well i just choose not to. And she repeated it’s gross and I said well the phones you use are mined by children etc . Listing things we use that support ‘ bad things’. To which she responds ‘ well a phone is a necessity and your McDonald’s isn’t ‘ to which I say well there’s always pen and paper. Also I stated that the prophet Muhammad also traded with non Muslims who used their money to fund wars , does that mean he should’ve not traded ? To which she got silent.

We then had dinner and she went downstairs to order, and I asked my mate if there’s tension and I said I agree. We never spoke to eachother the whole dinner. Me and my other 2 friends laughed and ate and she was mainly quiet after . Just spoke a few times then left after she ate. I briefly said bye and it was awkward.

I honestly don’t think I’m obligated to boycott. I have empathy and donate towards Palestinians, which I’m not required to tell people when I’ve just met them a few times. And it’s okay for your other friend ( who’s shopping in Zara and for me to say I do shop there , but when I mention McDonald’s it’s a no ?)

AITAH for saying I don’t boycott and causing tension ?
