3000 cups per day

assuming a 6 hours sale period from 3pm to 9pm

that's
500 cups per hour
8 cups per minute
1 cup every 8 seconds
non-stop for 6 hours straight

that is some crazy sales volume for ONE temporary drink stall

and chances are, there are plenty of competitor drink stalls in that bazaar alone
there is like someone selling balang drinks in every 5-10 stalls

assuming this particular stall garner 10% of the entire drink sales
that's like 30,000 cups PER DAY sold from this one bazaar alone
but not everyone will buy drinks. so let's say only 75% of all customer buy a drink
meaning that there is at least a foot traffic of 40,000 people

if the stall have a 5% of all drink sales
then the estimated foot traffic would be at least 80,000 people coming and going
from this 1 bazaar alone

i think 1Utama would not have this many shopper even on super busy day
