近日,一家自助餐厅贴出了收取“当日保证金”的告示牌,根据商家的规定,人数在10人以内,保证金需交100元,11人到20人,需要交200元,以此类推。商家称,此举是为了避免浪费,只要没有严重浪费,商家将全部退还保证金,但上述保证金需在当天用餐后及时到服务台申退,否则过后不予退还。对于这种保证金,相关法律法规并没有禁止性规定,因此,只要商家提前告知规则,双方达成一致后即可 Recently, a buffet restaurant posted the “day deposit ” signs, according to business rules, the number of less than 10 people, the deposit required to pay 100 yuan, 11 to 20 people, need to pay 200 yuan, and so on .
