English seems common in the groups of immigrants you come across too. I know people who've moved from France, etc, and there are lots of immigrants from various countries - many of whom speak their own language, and English as the second. Some go on to learn Finnish to a greater or lesser extent.

I've ordered food in restaurants, cider/whisky in pubs, etc, and had the server just reply back in English.

Me: "saisinko omena cidre?" Them: "Do you want ice?"

On the one hand it is helpful at times, but on the other hand it is deeply frustrating. 90% of the staff at the local newsagents has pulled me aside on a quiet morning and asked "Do you prefer English or Finnish?" I say "Finnish", but to be honest the conversations I have with the shop-staff are mostly them reading the total, and asking "would you like a receipt/bag/anything else?" so it doesn't help me in any real sense, but it's nice they offer/ask.

And yes, younger people know English well and will usually switch to English if you're struggling - unless they think that their English is too bad (which it usually isn't).

Alcohol is very expensive though!
