I guess i mite be unlucky as went to a few shops with unfrendly service etc but will give my honest input fore experiences i got. This is for TK photo Funan. Went there couple of months back, wana purchase 85mm 1.8 USM. Chats as followed:
Me: Can i try e lens?
Sales: If you wan to buy den can try. (I felt weird as cant try even before i decide to buy?seems funny as most shops allow me to try even before deciding. Nvm as maybe its their policy)
Me: Whats e price? and sales quoted me just abit more den other shops, no probs as not carrot me alot.
Left e shop as wana decide my purchase.
Few days later due to no other shops has stock except the holy shop upstairs but quote me a higher price, i decided to get frm TK photo.
Me: Hi can i try the lens?
Sales: Same guy again say if wana buy can try.
Me: OK no probs i got intention to buy.
Tried the lens shot a few pics quite please with it. Begin to check the lens thoroughly.
Sales guy got abit impatient as i check the lens by looking through the lens to check for any defects.
Me: Can i borrow a Jet blower(watever you call it -_-)
Sales:Sure
Me

i saw a white line across the lens when i see through e lens hole moving between light areas and shaded areas in e shop) There a white line across e lens sir.
Sales: Its dust.
Me: (I tried again and unable to jet blow the so call "dust" away) R u sure sir its just dust as its a white line.
Sales: U dun need to see so long one, e more u see e more dust get in as my shop here los of dust therefore wil make u more unhappy when u see longer e lens etc.
Me

I tot to myself he isnt sure as wel as im not too sure but who wil be in peace of mind buying a lens lik this as it is stil money to me even less den 1k)
Me:Thank You Sir but i will not buy it.
Sales

Nasty look he gave me) and say is ok you dun buy but it is lik that as is dust.
I really feel this is lousy customer service and also i do not feel good about the product like this.
P.S: So far already kana like 2 shops givin me such unfrendly services..mayb i suai go in when they having PMS period timing...
