2 hours is the limit.

I was unaware that you could use the same PP at multiple
restaurants within 2 hours though. I've never tried it. I will typically grab a bite to eat at one restaurant on one PP card and use my other PP card at the other one for takeout (I have one from Amex Plat and another from Chase Sapphire Reserve), because I figure it makes PP less likely to crack down on something like this.
