Sales Event Aftermath

Last week, i burned calories at the Singapore Expo Sale for Timberland.
It was a 3 day event and i happily went to sign up for all 3 days.
Thanks goodess the welfare was good. Got 4 days time-off for that.
The sale event was fun and nevertheless, experiencing.
Some funny questions, do hit me when i was selling footwear:

C- customer, M-me, myself.

C- “Hi, can i try this pair on my size?”
M- (thinking to myself, ‘ya, and your size is?” like i know your size like that)
“Oh, can i get your size mdm?”
C- “Hm, what size is this?”
M- “7, mdm”
C- “Oh, let me try size 7 then.”
M- “ya, this is size 7, you wanna give it a try. If it fits, i get you a new pair?”

(duh!!)

C- (looking at a pair of shoe)
M- “Hi, you wanna give it a try, its the last pair already.”
C- “Oh, do you another color?”
M- “hm, no last pair already, no other colors”
C- “Hm, do you have size 6.5”
M- “Hm, this is the last pair already and its 6.5. Can give it a try.”
C- (fits well and happy and contented)
“ alright, i’ll take this.. try on another side”
M- “Can, let me pack it up for you, thanks!”
