I think you're simply not used to it. Meals are almost always paid at the table here in Canada. Basically, the bill comes out, server either has or will come back with the machine, enters cost, hands it to you. You tip on the machine, tap, done. For higher end stuff or groups you break the $100 tap limit, so it's insert and enter pin, but it's still quick.

The speed of it is quick, and it also gives a good chance for wrapping things up (can we get this packed, thank-yous, goodbyes if it's a bigger group, etc).

Of course, it may also help that we have chip-and-pin and tap pretty universally, so we rarely hand our card over to anyone - having the server take the card is incredibly strange for me when I'm down in the US.
