Restaurant coverup or true? Blue mould

[Justweemammy]

Friend ordered raspberry and white chocolate cheesecake. First bite tasted bland and slightly warm. Then we noticed what looked like a 4mm area of fluffy blue/green mould at the outside edge. Ate no more. Waitress claimed other people noticed it too and it was just the fruit inside the cheesecake. We said raspberries are not blue/green unless mouldy. Manager then arrives with different explanation, saying “chef says it’s not mould as freshly made yesterday. It’s a reaction with the pot they use to make it”. No charge for the cheesecake.
Thoughts? Anyone heard of a bowl etc leaving a fluffy green stain on cheesecake?? Why would you use such a bowl in a restaurant if it makes it look like mould?!

Fur = mould. Did you take a photo?
Have you checked their food hygiene rating online?

This reminds me of my first waitressing job over 25 years ago when I found a mouldy strawberry cheesecake in the fridge.

As I stood over the bin, about to chuck it away, the chef boomed at me "What the hell do you think you're doing?"

He snatched the biohazard specimen out of my hands, scraped off the mould, bunged on a few less blue strawberries and covered it with jam and told me to get on with serving it up.

Thankfully they're no longer in business

@Lovemusic33 - they weren't charged for the cheesecake :)
