Zach Kanoff from Affordable Seating commented on the findings:

“With the ever-growing rush of customers and pressure of working in hospitality, mistakes will be made. It's shocking to see a high volume of complaints regarding food hygiene.    

Food enthusiasts must take extra care in remaining vigilant in spotting any potential food hygiene issues, such as dirty plates, glasses, or cutlery, food not being warmed through, and meat not being thoroughly checked before eating.

If a complaint is necessary, it’s worth making one. Hopefully, by doing so, the establishment will improve the quality of its food, making the customers happy and reducing the number of negative reviews.”
