I have a money clip, a smart phone and keys. Phone needs to be in a front pocket so that I don't sit on it and break it. Keys need to be in my front right pocket so that they are accessible and I do not sit on them and never sit again.
Thus my billfold must go in one of my rear pockets.
For me, the money clip and keys are in the right pocket, and the smart phone goes in the left front pocket.
The keys and money clip are distinct enough that I have no problem pulling out the right thing. And the keys are not going to damage the money clip like they would damage the phone.
Same here. Phone in left. Keys, money clip, change, pocket knife and everything else in right. I try very hard to never put anything in my pocket with my phone. mostly for ease of access but also to avoid scratches.
Phone is too big to be comfortable in a pocket, so I use a horizontal belt clip, which is pretty unobtrusive, especially if you wear a jacket or loose shirts. Wallet and keys in front pockets, leaving my arse free for comfortable sitting.
Thus my billfold must go in one of my rear pockets.
