Do they fold clothes nicely for wash and fold?
Depends on the tier. Premium pickup services (us, others): hand-folded by trained staff, items folded along their seams, t-shirts square and flat, shirts on hangers in protective bags, trousers with matched legs, undergarments paired in matching sets. Mid-range walk-in shops: machine-folded or loose hand-folded, neat but not seam-aligned, items typically thrown into a single plastic bag together. Cheapest 50-70 THB/kg shops: minimal folding, items returned semi-flat in a bag, sometimes still slightly crumpled. The difference is genuinely visible when you receive the bag.
