That is very commendable on the part of Anglo-Welsh. I have sympathy with them as they still have current expenses, wholly or partly covered by your payment for this years holiday (which you are not taking). When you take next years holiday, they will have no income for that week but still have the associated expenses!
But they have ‘not delivered’ not through any fault of their own. This really is an unprecedented, global, situation. I think we should view this pragmatically. I am happy with a voucher. I should have been on the Broads last week. It didn’t happen. As the previous poster said, ‘next years holiday is sorted’!
