TTN, why? I am with 5aday.
If you are suggesting my being able to afford a cruise means I don't need a discount?
Consider this:
In an organisation to which I belong we can claim certain expenses which are funded by the members ' subscriptions. Now one person does not claim his expenses as his contribution to the organisation. Ultimately it means that each members subscription may be a few pence less.
OTOH I claimed every penny due. I was refunded a few months later. As my expenses had been paid from current cash I had no need of the refund. I paid the money directly to our charity account with a beneficent chancellor adding 25%.
I told the other, by not claiming his expenses, that he was reducing his ability to contribute to our charity.
The same principle applies to any discounts I can get.
