To be miffed and slightly peed off that

[SoleSource]

The Co-op near me have stopped selling cotton buds.

Health and safety gone mad?

(waits to be flamed)

Maybe no-one bought them?

Why would anyone flame you?
Yes that is annoying but it's a small shop so maybe they weren't selling enough to justify it. Co ops are awful for obviously doing NO market research and never having things you need but selling stupid things you'd never buy from a corner shop (cotton buds is one of them!)
