Here's my $20 lesson: If you see so many poor reviews, why do you think your experience is going to be any different?
Went in around lunchtime to replace the battery of my The Citizen quartz.
Me: "how much does it cost to replace the battery?"
Owner: "$20, see you in half an hour"
30 minutes later...
Owner: "watch is still not ready, by the way, how much did you pay for it?"
After learning the price, the owner "jokingly" said he should've jacked up the price of the battery replacement.
Another 15 minutes later, owner brought the watch out and murmured "how much should I charge for this repair" then told me it's going to cost $30 because, wait for it, he had to put the band back on, $20 for the battery, $10 to put the band back on........
Obviously, I disagreed and refused to pay $30. Then the owner started forcefully taking the watch away from me and said "give me the watch, I'll take the battery and band out". I again refused, five minutes later, the owner conceded and accepted $20, but not before telling me (no less than five times) to NEVER COME BACK TO HIS STORE, HE DOESN'T DEAL WITH PEASANTS (I found this part a little ironic, but anyway).
