In an economy cabin, wherever possible, passengers should be encouraged to visit the galley for their needs outside of service times. This will enable to crew to better serve the cabin as a whole instead of the vocal one or two who take up disproportionate amount of the cabin crew's time, which is not fair to the rest of the cabin.
Whilst I tend to agree with this statement as it does make logical sense, SLF are NOT mind-readers, and until something is communicated to them to this end, nothing is going to change.
As a quiet non-call-bell pressing pax, I would suggest that if CC wish pax to behave in this manner with the call-bell, then
inform them, otherwise, it will forever be known as a "call-bell" where you can receive additional service from your seat; and so the 5% of pax that are abusers of that priviledge will continue.
