The honey we are selling has two sizes: small one is 550g and the bigger bottle is 750g. N the thing is i actually thot the big bottle is 1kg all along...w/o realising it. then today i keep pushing the big bottle as it is cheaper. Then one of the customer had bought tt big bottle n after she left, i look at the bottle again then i realised that i have been saying the wrong thing to customer...argh`~~too late... I feel so guilty siaz...wat if she found out after that and feel cheated? but i am really 无心的...haiz... 怎麼辦...~!~!~??????
