Reasonable bank charges - do they exist?

We have finished the purchase of a small property - and the moving - thank goodness. During the transaction we were forced to make several 'telegraphic transfers' at £30 each for bank charges.
It seems to me that the charges were excessive, the money was transferred electronically - certainly no telegrams were generated! When I suggested that I could simply take out the cash and carry it over the road to the solicitor, as he did not want to take a bank cheque or debit card, that method was also refused.
When a mortgage is arranged, few people will back out due to bank charges - so the banks know they have a 'captive' client, who will accept nearly any charges imposed.

Tesco and Sainsbury do the same - that is comparison and not illegal. It is good business to know the charges of one's competitors.
However it would be illegal to colude in fixing prices amongst a cartel of suppliers of a product.

The large company supermarkets have very good lawyers, who keep their actions marginally on the correct side of the law. As do airlines and other large businesses.

Many businesses can calculate the likely, and maximum, penalties which may be imposed. They can then calculate it in as a business cost and consider if breaking law is profitable.

The same is true of all penalties for illegal activity. Penalties should match the person to whom they are being applied. A £100 fine means a lot to some, but the cost of a meal to others.
If there were effective, meaningful, penalties for the frauds which many MP's have carried out - and mostly got profitably away with - they might not have attempted them.
At least it has taught the UK public that few of their politicians have morals.
