Seriously, I've seen this happen a couple of times. I always dread when someone joins at the last minute. Anyway, my most annoying experiences are always during nightfalls. Getting 5 strange coins or useless ascendant materials is brutal. Especially when the other people get exotics. Also, this hasn't happened to me yet, but I dread getting three energies from a Crota kill. Why's this stuff even allowed?
