Yep. Whenever I play, which is rare because I usually GM, I tend to take equipment nobody else will.
For instance, one of my 2e thieves had a bag of marbles. Everyone else in the party laughed at him. Until, as luck had it, he faced about 40 kobolds at the edge of a cliff alone.
I had a swashbuckler that had a penchant for dried fruit, and always kept a supply of raisins or other dried fruits on his person.
I also have a penchant for using spells in odd ways, such as the time my 2e wizard convinced a kobold he was interrogating tha the was a god using prestidigitation to make a shower of glitter when the kobold lied....
