If your shop is so small and your location so central that you can only sell good brands in great condition, with a fairly high price point, and you have to dispose (at your expense) of a lot of donations as a result, then you have to ask yourself if your dream of a charity shop is feasible. The average American would wonder how much of the charity's takings were being spent on rent if they could walk to the charity shop - a high street location comes with a hefty price and lack of parking is a huge problem. You would not make enough to pay the rent in many urban or suburban areas selling second hand clothes, shoes and bags alone.
I think many UK donors would assume charity shops have their act together when it comes to disposal of items that can't be sold and securing a location with a reasonable rent. I think some on this thread who are put off by the charity shop workers they have encountered can be forgiven for assuming charity shops really have done the maths and therefore sending every single thing they can cram into a big black bag.
Goodwill does not have a $1 rail - they have outlet centres where deeply discounted stuff goes if it fails to sell even after a reduction from the original $5.99 (an average price for clothing items) to $2.99 in a store. Prices are lowered at intervals until an item's four weeks on the floor are up in the case of bags, outerwear, dresses, tops, jeans, trousers, footwear.
If it doesn't sell in the outlet centre, stuff gets boxed and auctioned off in lots. I know a woman who buys boxes of unsellable T-shirts to make rag rugs that she sells for quite a profit even after sanitising the clothing. Children's books, soft toys, CDs, video cassettes, albums, ties, belts and hats and a few other categories are priced at $1.00 or 50 cents. The whole shop is a bargain rail really, but the outlet centre takes it to a whole different level.
When I see comments about 'lowering the tone', and having to price at a certain point to break even, afford rent, bills, and wages, etc., I get the impression that charity shops have not really taken reality into consideration. Traffic and volume are key, and accessibility too. Charities are important - though it really is a scandal that a hospice is not adequately funded by the NHS - but it might be that some other business would do better in the sort of locations that are available, and charities clubbing together, finding suitable accessible locations, and rethinking the price structure might achieve economies of scale and more revenue.
The loos in Goodwill are used by the staff and the customers. All cleaning is done by staff. The loo can be used by customers because that is a way to keep people in the shop, loading up their trolleys, and thus moving the merchandise. Whole families come and shop. Many toys are bought by parents who want to keep children happy while shopping. Letting customers use the loo is a solid business decision.
People also use Goodwill to access the computers, search through job listings and do interview training. They could be there for many hours a day. The one I go to also allows quiet and sober homeless people to sit in the book section at the front where there is a table and some chairs, in winter or in heat emergencies in summer. They also use the loo. The place is a charity shop after all.
Alltoomuchrightnow, going alone to donors' homes sounds like a very risky undertaking. I hope you had no bad experiences.
The Salvation Army sends out trucks here to pick up donations like furniture. They schedule your pickup and add you to their route when they are in the area. I will be getting rid of a big teak craft table thanks to the SA in four days. There is a LGBT charity shop within walking distance of me (just under two miles) where I once bought a really nice coat and a pair of sandals - it also sends out a truck to pick up donations of furniture. They prefer dining room sets and vintage furniture or I would have had my big craft table picked up by them. They carry higher end stuff than Goodwill and they have some experienced furniture movers who won't scratch your valuable dining room set.
