One thing I don't understand is, who accepts these vouchers for non-food items? Asking this as someone who is not familiar with this particular system. I lived in countries where I got meal vouchers, but every place that accepted them only allowed me to buy food with them, and they outright refused to sell anything that can't be eaten (if they even sold anything like that)
