I was looking through The Official Manual for Operating in the SPSV Industry (Ed. 71, 2018) for something else and found this little paragraph on 'Professional Presentation" on page 71. Might be useful to some as the weather improves

Professional presentation
An SPSV driver’s attire and personal presentation is as important as the cleanliness and tidiness of their vehicle in portraying a professional image. Drivers should dress in such a way that their professionalism is immediately apparent to all prospective passengers.
Clothing should be smart, clean and comfortable. SPSV drivers may be required to pick up or drop off passengers and luggage in locations such as hotels or office buildings, where more formal dress is expected and items of clothing such as shorts, vest tops or tracksuits are inappropriate.
I guess it could open to interpretation whether you 'should' or you 'must' dress professionally. Has anyone every got a ticket for wearing a tracksuit or shorts? What about those trendy shorts that go down to the knees?
Could you get away with going barefoot since it's not mentioned? Or worser, hippie sandals with socks
