All this talk of slim wallets has me flummoxed.
I deploy a fat bifold, stuffed with notes, receipts, too many bleedin' maxed-out credit cards, a keyless entry card for my Sydney apartment, a keyless entry card for my Shanghai apartment, two driver's licences (Aus and Chinese), other miscellaneous cards, SIM cards, a pic of my babe, business cards, public transport cards, Jesus H. Christ the list is endless.
The damn thing is so stuffed with crap sometimes it won't stay folded. It's so turgid it makes my John Thomas jealous.
Anyway I just cram it in my front left trouser pocket and sartorial lines be damned. You have to draw the line somewhere.
