How it's used
Originating from nautical terminology regarding a ship's draught, this phrase has evolved into a common idiom for price gouging. It is frequently used to criticize businesses that charge exorbitant prices compared to their actual costs. You will often hear it as the punchline to the riddle 航空母艦, where the answer is 食水深.
Examples
That shop has such a huge profit margin, who would patronize them?
They have a massive markup in their business and are always ripping people off.

Common phrases
to have a very high profit margin
Common mistake
Do not confuse this with the literal meaning of water consumption, which is simply 食水. The figurative sense specifically requires the adjective 深 to imply the depth of the profit margin.
