case 1: he's property angent, and someone buys some super
expensive penthouse means he get a big commission. that's his job,
he just happy that he earn some big bucks, so he tell u guys that.
it's like u work in some company, u did well for the yr, boss give
u 4 month bonus while others only get 1 or 2 months, u will also
tell u friend cos u are happy about that, rite? As a property
agent, besides giving professional advice to his customers, he
should please them too. Attitude does matter when it comes to sales
job.
case2: this maybe really those type of ppl who lick rich man' ass
like u said. And u said "brag", so maybe he's not really that close
to those rich guy.
case3: i dunno if that rich guy is really close to ur fren. If they
are really close fren, i think it's ok that ur fren go help him
settle down. cos it doesnt matter he's rich anot, if his close fren
who's not rich, just came to singapore and want to look for a HDB
flat to rent and settle down, he should go help too.
