Life / Some Polish people start imitating English. What are their reasons for doing this? [5]

Sometimes when I'm walking in public with my friends (speaking English) I notice randomly some people start imitating words or phrases. Most recently somebody imitated "I think so too...hahahahaha" after my friend said it loudly. It's really annoying, I hate their horrible accents and I want to know what are their reasons for doing this?

Food / Electric Grilling - I highly recommend it :) [30]

I bought an electric grill a year ago, and it was the best 60zł i ever spent (@ LeClerc). Now I can make burgers and lamb kebabs like back home and on tv, great for turkey grilling and thanksgiving food too, I highly recommend it :)
