Apparenty cabin crew on an Eurowings flight from LHR to DUS would not accommodate her request to make an announcement of her condition and at least attempt provide a peanut-free environment, so she took it upon herself to buy all 48 packets of peanuts that were catered for her flight for a total of EUR 168.
She just paid for the peanuts but didn't take possession of them and later tried to claim reimbursement for the purchase price which EW refused.

Williams said the cabin crew refused her request to make an announcement. She said a flight attendant told her that it was against the airline's policy.
"He wasn't even looking me in the eye. I think he was getting frustrated I was holding up the line," Williams said.
The cabin-crew member also appeared not to understand Williams's allergy — she said he asked if she needed an inhaler in case she had a reaction.
Williams discovered the airline would be selling peanuts on the flight and felt the only solution was to buy every pack available."I said: 'I'll buy them all so you can't serve them. I don't care how much it is. If you're not willing to help me this is the only thing I can do,'"

This pretty minor customer service lapse now gets EW/LH some bad press. Already German news outlets have picked it up, and the tabloids surely will have a field day.
