This is actually bullshit, if it was a complaint, and not just a discussion.
It's your home, not a professional card room. If you have two tables, you've made a significant investment in tables, chairs, chips, cards, etc. I think the average home game player has no idea how much money goes in to putting together a decent home game setup. Sure it can be done cheaper, but not cheaply. If it was a real complaint, let them host and see if they provide an array of TVs that can be seen from every seat.
