Earl Grey or cheap tea, does it really matter?

All of this week and last week I'm working at a client's office in west London. So I've been away from the sanctuary of our office now for a while. At my usual office I have bought some nice Twinings Earl Grey tea bags. Definitely a favorite of mine.

When I started working at this office last week I had to resort to a difference tea that tastes less good. The first couple of cups were all a disappointment but addiction to caffeine probably pulled me back into the kitchen for more cups as the days got on. I drink about 4-5 cups per day and at this stage I don't even remember what good tea tastes like. I actually enjoy this cheap tea just as well.

Because one drinks such vast amounts of tea the taste just becomes what it is and it's only when you change from a quality tea to a cheap tea that you notice the difference. The question is then, as long as you stick to the same tea does it really matter if you drink fancy Earl Grey or cheap industrial tea? Surely the health factor is negligible but the price difference isn't thus going for a cheaper tea would be smarter? And by drinking cheap tea, when you a precious afternoon tea at the Ritz you're going to enjoy the tea even more.

Or should I be stoned and lynched for wasting thinking time on this?
