Narrative:

First officer was preoccupied with personal shopping on-line before push back. He had a tendency to put in the minimal effort during the whole trip. When we got the pushback; he was behind the whole way out. (I am a little too conflict averse; and should have confronted him earlier about this problem).anyway; we were going to have to deice; ramp was wet; but not icy; so I planned to taxi to deice pad on one engine. After first officer got #2 engine running; I asked him to call for taxi and to request a left 270 turnout rather than starting with a turn into the operating engine. He was having trouble copying the clearance and deice frequency; and never did ask for the left 270; so I finally keyed the mike and asked for that myself.started west to hold short of H at the west end of the ramp; where I stopped as instructed. First officer was still back at the gate and I was basically solo. He still had not copied the deice control frequency; and was now looking for it on jeppesen FD pro while I patiently waited. Second frequency he tried worked; we were told to taxi to the C1 pad for deice. Here is where I made my mistake. We 'always' deice on the bravo deice pad; I had both hands full of airplane; saw that C1 was at the left end of the pad; and turned left toward the deice pad [we normally use] to the spot at the left (south) end of the pad. Ramp hollered at us that we were supposed to turn right into the 'charlie' deice pad. I was able to make a 150 turn back to the right on hotel; and into the correct pad.ramp and iceman were having a discussion that I was the 7th airplane that day to turn the wrong way; and suggested that iceman emphasize in their instructions that it would be a right turn into the charlie pad. I was a bit overloaded and basically taxiing solo without much help from my first officer; but much to my chagrin 'expectation bias' bit me in this case.
