Just as an addendum - whilst the process may be relatively easy, especially for citizens who are used to applying for and using them, most first time travelers into Hong Kong/Macau do not even know what it is that they are entitled to. And even for some multi-time visitors as Chinese travelers are still not that used to travel outside of their own borders.

Many have been turned away at the border as their permits have expired/number of entry permitted for has been used up/other reasons as they just don't realize/know.

PLUS more importantly - it is as per my original suggestion OP horniez to double check if Shekou ferry pier has these agents who arrange to accompany Tour Groups; because chances are that his traveling companion only holds an "L" endorsement - which is the easiest to apply for/most common granted by the PSB.
