Should I make that street food vendor pay or not !!

I am currently very angry, I went to a street food vendor for first time and was waiting in line from like you can say 10-15 minutes, I was wearing shorts therefore mosquitos were biting too

Now when he was done making those burgers, He started giving orders and in last 2 were left amd my order was of only one , So another guy had order 2 and he said to me aapka bnana pdega

So I was like in 2 mein toh mera ek pehle ka hu, During this Convo he was giving another order amd those guys were saying we came earlier and I was like aapse nhi iss order ka khe rha hu so in confusion I forgot that the other guy who has ordered 2 came much after me

I realised it later but told the vendor rhn do and left

Now after walking for 2 minutes I realised the exact moment the other guy came

I would've gone back and beat the shit out of both vendor amd customer alone but still went back to home

Now I am planning to complain against that street vendor for encroachments and other fuckin thing I can do with municipality

Reason being that vendor knew , I was confused but he knew and was smiling that smirk smile

Tell me shoulder I do or not , Cause my anger is justified
