anything can be analyzed to the point where it evaporates into absurdity.
for example: the buzz phrase "at the end of the day".
eg: "at the end of the day, we all benefit".
does this mean only at the end of the day "we all benefit"?
therefore, does it mean that only in the nanosecond before midnight we "benefit"?
even the final nanosecond of a day is not the very "end of the day".
therefore, does "at the end of the day we benefit" mean "only in the infinitesimal instant preceding midnight - - we all benefit"?
no it does not.
since all instants of time are contained within some day or another, then there is no end of any day, because transitions from one day to the next are points of time with no duration, therefore they do not exist in real time,
so there is no end of the day, and therefore no one "benefits" ever.
-------------
when an advert says "you save 20% off the price", it is absurd (to me).
example: a dumb salesman says "you will save 20% off the price" (of a $100 item.)
salesman: the price is reduced by 20%
customer: so what is the price then?
salesman: $80
customer: ok, the price is $80, and you said the price is reduced by 20%, so the price is $64?.
salesman: errr yeah i guess so.
customer: so if the price is 64, and it is reduced by 20%, then the price is $51.20?
salesman: uhhhh i suppose so.
after another 16 steps the price is $1.80 etc.
customer: ok i will buy one.
also, the correct terminology is to say "save 20% OF the price", not "OFF" the price.
whatever.

in australia, our smallest coin denomination is 5 cents. if something costs eg: $1.22, then it is rounded down to $1.20. if it costs $1.23, then it is rounded up to $1.25.
therefore, it is possible to fill up your petrol tank for free at the petrol station (gas station).
all you do is put 2 cents worth of petrol in, and go in and pay 0 cents, then go out and put another 2 cents in then go in and pay again etc until your tank is filled.

there are hundreds of ones i have seen but that is all for now because i am not sure i am entirely on topic.
