My DP and I spend nearly every evening like this - I'm on my iPad, she's on her phone or laptop, we're watching TV at the same time, and yet, we have great conversations (I hold up the iPad to show her something, she hands me the phone or sends me a link, we discuss while the TV is paused, and continue once we're ready). We've done it out in public, many times - frequently one of us is reading something the other one sent them, or one is checking the weather and transferring funds while the other one checks out maps and info for an event we're heading to. If everyone's OK with it, tech can be fine.
Now, if this happened while we were at a pricy restaurant on a date or something, I think I'd be offended - but at a routine, 'pit stop' sort of meal? Especially breakfast, where some of us aren't awake yet? No big deal as far as that goes, in my family.
