'the swiss' just abolished (per july-1-1999) all discriminatory (formerly directed against imports, to protect local viniculture) alcoholic taxes/duties for spirits and all alcoholic beverages

So, the timing for giving up serving champagne on the ground, when departing from Switzerland, isn't very logic

... and I wouldn't mind to have a bigger turnover of champagne-deliveries to ZRH-airport ... so please inform your airline and ask for it - thank you.
