Well 18 hours is longer than the test should take. You do need to run Memtest for several passes (some people say seven) and that can take several hours. Also you have to test each module separately, so if he's got two 512s then it will take twice as long.
If they want to _charge_ him for 18 hours of labor for the memory test, then that is wrong. It only takes half an hour to set up the computer for the test (at most) and a few minutes to switch memory modules if there is more than one. The rest of the time it just runs unattended.
However, if they are just trying to explain that they cannot run the test while he waits, that he needs to leave his computer with them for a day, then that is reasonable. Especially since the memory may pass the test and they would then have to do more diagnostics.
