Final answer:
Double-breasted jackets serve a dual purpose: they protect the wearer from hot spills and splatters in a food service environment while also providing a professional appearance that echoes historical industry practices aimed at highlighting cleanliness.
Step-by-step explanation:
The purpose of double-breasted jackets is to both protect the wearer from spilled or splattered hot foods or fat and give food workers a stylish, professional appearance. The design aligns with historical efforts in the food service industry to ensure hygiene and safety are at the forefront.
Cooks and food workers often wear uniforms that are not only practical in terms of safety but also convey cleanliness and professionalism, mimicking medical professionals' white uniforms. This is in line with the restaurant industry's broader practice of using glass, stainless steel, and white porcelain in their design to showcase a modern and hygienic environment to customers.
