I don't remember exactly where, but in some dungeon, 4 out of 6 of my pokemon got killed by trainers. I didn't know how far I was from the exit, and I obviously didn't want to go back.
So I used my remaining revives on them.
30 seconds later, I run into a doctor. The two pokemon that weren't killed easily pwned him.
FUUUUUUUUUUUUUUUUU I MEAN, LIKE, I WASTED PRECIOUS MEDICINE WHEN THERE WAS A DOCTOR NEARBY.
LOL. I hated when this happened. I would even ignore the doctors just to say "I won't have wasted those Revives and Potions in vain".
