christep: I didn't apologise explicitly to the Rainbow staff.

They explained their system had caused previous objections by other visitors. And the waiter did misstate what their cashier was going to do.

I conceded they were right after all after hearing the cashier's explanation and advised Oreck and ColoradoGal it's safe to sign the DCC slips.

I don't feel an unconditional apology is called for because their waiter did misrepresent what was going to happen. But I did advised other FTers in the restarant and publishing their system online here they are ultimately compliant.

I did let Oreck know his slips were going to be used in this DCC thread.
