In mens blazers and suit jackets, at least the better ones, there are extra pockets in the side pockets for change, keys etc. There are also extra inside pockets for mobile phone, theatre tickets you name it. Tailoring has changed to accomodate new gadgetry in trousers also.
Chinos are always a problem compared to jeans for change otherwise.
I don’t carry a wallet, I have a small case with a lid which opens and snaps shut for my cards. Cash is often unnecessary, where cards suffice. Most people in the UK do not carry large amounts of cash where it is seen as slightly suspect due to counterfeiting and association with illegal cash income such as drug dealing. Not to mention the risk factor of having it stolen or misplacing it. People line up at cash points for an evenings supply for drinking in bars, and the taxi home but apart from that…
People will take out money to show they have it when ordering drinks but you will never see it in plain sight of them on the bar while drinking as is commonplace in some American establishments.
I do have a shoulder bag for a laptop and books maybe a bottle of water, this is also a common sight.
