Correct, but consumer law ! what is that they might ask. we know it but how do they know it. only the management and supervisor level employee know that in inter.level hyper. mkts. can you expect grocery supermarket cashier to know this lows or do they obey the law ? That's the question we might ask our self's what the heck.. is this law for. small boutique even doesn't have this POS for our cards. we pay by cash if it's not consumable we have to through it on his face. :)
