Moving Dealer Button

[Linake]

Hi, I am new to the forums and relatively new to poker, but while playing outside of my reg. casino I was confused by a dealers button move.

Limit Hold'em
I'm seat 7 and SB, Seat 6 decides he doesn't want to play his button and gets up to take a break. The cards haven't been dealt and the dealer moves the button to me, NOW I'm SB and on the button at the same time. I nicely questioned the move of the button "I'm sb and dealer?" the dealer insisted this was correct. I let it go. Next hand guy in seat 8 is SB and button(button was moved to him the next hand).
To me this seems wrong because once the flop hit(when I had been the SB), guy in seat 8(BB) was first to act, also, where does the rotation of being SB and on the dealer button stop?! (I actually was going to leave soon so I didn't get to stay and watch to find out... kind of wish I had).
Thanks for reading, any thoughts? [img]/images/graemlins/smile.gif[/img]
