Rocket left its season by 76% - and it was not noticed at once
A restaurant chain put the rising price of greens down to the season. RestoAudit compared it with the norm for the same month in past years: 3.80 € against 2.16 €, a 76% deviation that held for the fifth delivery. The chain switched supplier for two weeks and fixed the price with the previous one in parallel.
