Oh yes, sometimes during class, you won't know what to ask,
until a genuine "I didn't know" mistake happens. Would the customer
be able to get an exchange for the stove, so that at least can
placate him?
When was the last time you returned to Sg? I guess...if one is
making a decent salary and not having to worry about money issues,
then things here would still be considered bearable, and there are
some nice things which we tend to take for granted (eg security and
convenience). Why don't you take a break, come back here for a
month or two before you decide?
