As has already been said, banks love to siphon cash under the guise of "fees".
Up to 4% of all payments ever made, are siphoned even though it requires the SAME electronic process to process a £1.99 payment as opposed to a £10000 payment.
So if you ever have to pay someone £10000 the banks are laughing all the way to the bank LOL because they magically earn a £400 bonus, PLUS they also take a fixed fee for every payment on top of the percentage cut IIRC!
Trying to minimise the amount of your money, and their money, which is siphoned off by a bank. Cant believe they just siphon 4% of ALL payments and it happens every single minute. Horrible.
Imagine this on a small scale economy. Imagine Two sellers who are also each others customers. They have £100 each and they buy each other's produce. They trade with each other evenly, except they use the evil debit card.
The first full transactions they each make, they will be left with £96 each.
Second transaction, they will have 92.16 each, in the economy.
third transaction, they will have 88.47 each.
and so on.
Sooner or later a considerably large portion of the money in their economy will have been siphoned by the bank and the two trader's economy is now completely collapsed and the bank is empty because they have implemented a cashless society and banker is nowhere to be seen because he's sailed to Hawaii and is chilling on his yacht sipping £100 cocktails.
