Food / Best hypermarket to shop for foods in Poland? [21]

Which one do you prefer to shop at? Here is what I found out...

Carrefour - good onion bread
Auchan - looks like a food warehouse
LeClerc - cheap, good meat selection, onion bread...ok
Real - good candy selection, can be overpriced
Tesco - open 24/7 :) soft bread
Bomi - overpriced but nice international selection
Alma - same as Bomi
Lidl - same as Aldi
Biedronka - good deal on shrimp, only has candy and moldy fruit, overpriced same as Lidl

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 :)

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?
