If I recall rightly Concorde pilots often took control from autoland and landed it slightly off the center line.

This was to avoid upsetting the passengers and to ensure the champagne didn't get shaken too much.

I don't think you were allowed any service items during landing, so this can't have been true.

Could be referring to the champagne still in bottles. How long does it take for a "shaken" bottle to return to "won't explode everywhere when you open it" state, anyway? Does the low pressure in the cabin make it more prone to erupt?
