Lfs is a business entity, it is offering a niche service for a small group of the community. Its success depend on the patronage of the said group. That said, profitability is their aim and with increase profitability comes more stocks and wide range of equipment and accessories.
The success of this lfs depend on the community it serviced. Successful reefer are the best return customer. Newbie need to seek more information from the forums and such than from lfs as they are asking question that lfs owner cannot answer on the spot accurately. Newbie to the hobby who fail are the worst PR the lfs will have to encounter, they do not understand that it is not the lfs job to advise newbie on what to do as the variable is just too wide to cover in the few times customer and business owner/staff meet.
The best thing if any experienced reefer encounter this situation is to have a piece of scrap paper on hand and write down this forum address on it and pass it to the newbie, thats it. If you are on friendly term with the lfs, try asking if they are willing to spare a space, an A4 size space and place this forum address on that paper and stick it on a prominent place, ie cashier counter or the entrance/exit door.
And for me, no, I do not interfere. You do not want to research it, its your problem, not mine. I have experienced colleague calling me at the oddest hour to spoon feed them, I always insist to them to join Reefcentral and read all the info here. Those who dont, quit, those who do, realised what I have gone through and repeat the same advice, join Reef Central.
