If you're on a first date with someone who is more interested in their phone than you, do you get up and leave?

I would pause, then nod and glance at their phone asking them if this was a good time. It gives them the option to end the date if that’s what they were trying to do, or offer an explanation as to why their focus has been on their phone so much. It also brings their attention to what they’re doing so if they want to continue the date, they’ll be less likely to give their phone time over me.
