The guy at Le Labo is a right prick, i've had telephone conversations with him that have led me to want to pepper spray him. The lady, Sumaya is fantastic, she sent me out 8 - yes EIGHT! 5ml vials (she said they were 10ml, but I swear they're 5ml) of Rose 31, just because she would have had to throw them away due to their silly sell by date gimmick. It's a shame you didn't get served by her, she would have probably been fantastic. (She sent me those, one 5ml vial of the Iris, and sprayed cards of all the rest!)
If you do head to London again, please do go into Liberty, but just avoid the Le Labo counter (remember, just a concession, Liberty have no control over the staff!) otherwise its fantastic!
