Forest Hill Cars shouldn't have sworn at you but I totally understand their eminently reasonable anger.

You were totally out of order.

>>I decided that I would cancel whoever didn’t make it there first.

It seems clear that you didn't tell either company that they were involved in a race for your oh so precious favour/business.

Forest Hill cars sound professional in giving you a realistic arrival time. They could have given you a falsely optimistic time to get the business but didn't. They were honourable.

Forest Hill Cars are better off without you.

I hope they are reading this.

I have no connection with them.
