I lived in a shared house with 5 others. We had no central heating, no TV. We did have reasonable cooking facilities but I had an extremely small budget so my parents would take me to the supermarket when they dropped me at the beginning of term, and they would pay. I couldn't afford to supplement that with much, so I ate a lot of tinned tomatoes, pasta, tuna.... Mind you I don't think tuna is as cheap as it used to be, is it?
Also ate toast for a main meal whenever possible, with marmite for the vitamins. Went to any event that had "refreshments" anywhere, that provided some interesting experiences as well as a few meals.
I had no car, no-one I knew did (but it was Cambridge so ardly surprising). I took out the full loan (one of the first) and got really annoyed by people (many of these at Oxbridge) who took it out and bleated about how they put the whole lot into a high-interest account and made a profit.
I walked everywhere, didn't drink or smoke, and worked in all the vacations. I was anaemic and very thin, but relied on vacations for my mum to fatten me up.
My baby brother is off to Oxford this term and I am highly amused by his en-suite study bedroom with wi-fi, internal phone. My college accomm had bare brick walls, not even plastered, shared loo and shower between 15 people.
It is a different experience completely to my student days, but then people's expectations are higher and people are more used to a better standard of living, I suppose.
