i did suggest in a different charity shop that ordering clothes in colour order is not the easiest way to find your size., they didnt like my pov
They order clothes by the triple categorisation of type, colour and size in the second hand shop I go to most frequently.
For instance, women's long sleeved shirts are arranged on racks beginning with Small in white and progressing through blacks, greys, blues, purples, reds, oranges/peaches, yellows, greens, browns/beiges/creams, then on to Medium with the same progression of colours, and then on to large, XL, and so on to the bigger sizes. There are separate sections for short sleeved shirts, sleeveless shirts, sweaters/cardigans, fitness/sport clothes, dresses, coats and jackets, jeans, coloured jeans, denim jeans, work trousers, all arranged by both size and colour. They arrange their handbags and shoes by colour too, with men's, women's and children's separate, and all boots on the top shelf. Shopping there is a pleasure. You can go straight to the section containing whatever you're looking for or browse if you have the time.
Their book section makes me itch, however. It's all higgledy piggledy alphabetically speaking, but there is an effort to arrange it by fiction, cooking, pregnancy/baby/child development, self help, and YA and children's. The mess is not due to lack of volunteers. The shop is Goodwill, a charity that provides employment opportunities for people who are hard to employ for various reasons. They employ some students, adults with mild disabilities, people with a spotty work history, record of incarceration, etc., and are never short of staff. I go looking for specific titles or authors - it's my first port of call as they do uniform pricing on everything they sell and $2.99 for a book is a real bargain - and unless I am very lucky and one practically jumps out at me I come away empty handed.
The crockery section is a mess too but at least they don't charge for breakages
