Overall, coffee was the most profitable item across all three years, whereas tea generated the lowest income. In addition, while almost all products showed upward trends, the most dramatic increases were seen in coffee and pastries.
In 2000, coffee brought in roughly £70,000 per month, making it the top-selling product. Its figure rose steadily to around £100,000 in 2010 before peaking at nearly £140,000 in 2020. Pastries followed a similar pattern, more than doubling from about £40,000 in 2000 to almost £90,000 in the final year.
Other items experienced more moderate growth. Sandwich sales climbed from approximately £30,000 to £50,000, while cakes increased from just under £25,000 to nearly £45,000 over the same period. Soft drinks also improved considerably, doubling from £20,000 in 2000 to close to £40,000 in 2020. By contrast, tea remained the weakest performer, with a slight rise from £15,000 to £20,000.
