Wah... u guys manage to dig out such an old thread.
Anyway here's what i think:
The only two criterias i look for in a shop are service and honesty.
Generally, most lfs i came across are alright.
However, there are a few occassions when certain lfs are dishonest.
i.e. The lfs quoted me $200 for a prata which u can get it easily else where for $50-$80.
i.e. The lfs quote you accordingly to your age and the way you dress. My friend wears a suit to the lfs and got quoted $150 for some coral. Another fella walk in wearing a t-shirt and got quoted $100 for the same coral.
p.s. pls dun pm me asking which lfs i am refering to. Its not right to expose it outright but personally, i just stop visiting it.
That is my only blacklisted shop.
