You should replace 'You...'' in your response with 'From an ideal security standpoint one...'.
OP obviously does want to RDP to their machine, they stated as such. For most people, accessing a desktop-class machine from a mobile device isn't a significant issue.

Genuine question: how does that work though?
I would have thought (but perhaps I'm wrong) that the waiter does less work per person as the number of people at a table increases, so why would the percentage tip go up?
And as far as the bill goes, if there's only me, I'll likely stick to soft drinks. Whereas when there are more people in my group, I'd be much more likely to grab a bottle of wine to share, pushing the total bill per person up, and thus the tip.
