You can actually get accustomed to the bad taste. It happened to me. But then I started drinking coffee at work again and out went my nespresso machine.
The only office I know in our work where the coffee is decent is the one in Paris where they have a real coffee bar inside the office with a real barista (and cost-price pricing).
But in all the other offices we just have vending machines that spit out horrible swill.
Or you just have different tastes. Your taste isn't necessarily any better. It is just different. I like brussel sprouts and many find them disgusting. Doesn't mean my taste is better than theirs.
