If the bank takes a % of every transaction then every time that money is used to buy and sell eventually,in theory the bank will take it all.
And yet ironically, as above, G4S coming out to take your cash to the bank for you is SUPER expensive.
And banks also charge businesses for dealing with cash.
A quick search tells me that Co-op charge their businesses 0.55% cash handling charge

Plus £10 per month for the privilege of dealing in cash.
If you do more than £30k, SumUp are 0.79%.
So we're talking about less than 1p in the pound, your insurance is cheaper (because you're not getting broken into), no G4S or sending someone with £10k in takings to the bank (our nearest bank is 3 towns away now as they've closed them all down here on the Waterside in the New Forest).
Either the owner does it (time is money) or pays an employee the hour and a half plus petrol and parking. You're not getting change out of £30 for that.
Another quick search says G4S would cost for £20k, £29.50+VAT collection, £9 to deposit and any loose change is charged at 1%.
Of course, if you're running your business as a cash business, avoiding tax and VAT AND DUTY (let's not forget this is pubs and breweries we're talking about), that's prison time!
