Service standards in Singapore are sometimes a disgrace... there
are these everywhere in the world, however, bad service in
Singapore seem to be the norm rather than the exception 
Management need to recognise that bad service will cause the
downfall of their establishment even if they have the best
product.
Here, Edo sushi seems to have lost a few customers... and by word
of mouth, more will know... and after a while, their customer base
is eroded because of the rude staff.
I think before the management starts cursing the economy, they
should look at themselves and their own staff. Good service will
ensure a loyal customers who will come back or at least try to come
back.
Oh well, as a sushi lover, I'll give Edo at Thompson a miss. Looks
like they have lost a potential customer in me.. and if this forum
all follow suit, Edo may have lost a whole lot of revenue!
