PUZZLED??

today I got myself a HK watch for $72
bargained price, she dropped the cents for me... told me "today last day here...." and then I went "so cannot give me discount meh?"
frankly, I dun care u last day here or first day here, I JUST WANT MY DISCOUNT!!!
>.<

anyway then the conversation went on like this which made me a bit bit puzzle

"get the white one. can match the fair skin very well. next time can change the strap to black. but the black one, cannot change to white?"
"WHY?"
"dun match mah"
PUZZLE NO. 1... white can match black,  but not black with white?  what theory is this?

"so next time want to change. go where change?"
"dun worry. u see, I stay in bedok too. if u buy, I will put the contact number on the receipt, if u need to change the strap just call me"
"oh..ok"
"the battery can last like for 1 yr, we guarantee the battery for 6 months too. so u can also call me if u need to change battery"
"oh.. ok"
"but I think u dun need to worry la. the watch can auto shut de mah. so very battery saving. I think the battery can last 3 years"
*kua kua kua*
PUZZLE NO. 2....first u say can last 1 yr... then subsequently u said 3 yrs... so which is which??

so end of the day, even if u give me ur number, I also wont be using it lor... and so many years later, u might have "closed shop" le
then how?

stranded....
