I guess this should be a poll question, but this is not something that can be discussed when meeting someone new.  But after my last, I was left disappointed when I was told during our session that only one cup was offered.   I have established friendships where I know that is not an issue.  But when meeting someone knew, do you just cross your fingers or does anyone have advice on how to handle the topic so expectations are known beforehand?

There is literally a box labeled "multiple pops allowed" on each provider profile.  You can also spend some time reading reviews.
