Narrative: I was CIC for Area C while the supervisor was getting currency at sector XX.  There was weather everywhere!  Feeder said they had a cell on the north side of LAX so they wanted everyone landing LAX over KONZL.  Our TMU tried many times to call SOCAL TMU and ask if we could go over GRAMM but they would not budge.  We had no weather impeding aircraft from going over GRAMM.As it turned out; the supervisor working Sector XX was not working well with Sector XY and just let his aircraft run in to KONZL at 250 knots.  The sector 20 controller got spun by feeder and he had many unsafe situations as a result of having too many airplanes over one fix and deviations.  I eventually had to ask the XY controller to spin one of his aircraft and the XX controller to put 3 or 4 of his aircraft on southerly headings and give them to XY.  I felt the XX controller was jamming 20; and this was the only way to get out of the mess 20 was in.  The XY controller gave 20 some extra space and did a fabulous job with way too many airplanes and deviations.I would first recommend that feeder not be able to get away with unneeded restrictions that are dangerous for aircraft.  Secondly; I would recommend that controllers/supervisors/staff who only get 8 hours a month on a sector not get currency when there is heavy complex traffic such as during thunderstorms.  I believe that had a more aware controller been at XX during this time it would not have gotten so out of hand.One more thing to mention is that every Friday night in our area the supervisor leaves at XA:00 PM leaving 3-4 of our least senior controllers there to work until XB:45 PM when the [next shift] comes in.  There is almost always a CIC until XB:00 PM who can then leave the area with the supervisor at the OMIC (Operations Manager In Charge) desk and work traffic until XC:00 PM.  There are never enough controllers to work the amount of aircraft along with the complexity that occurs after XA:00 PM on Fridays.




Synopsis: ZLA Controller reports of weather deviations that were affecting the flow into SCT Feeder sectors airspace. Feeder Controller requested one flow instead of two due to weather. Previous center sectors were not giving the last Center sector the flow needed and was told by the reporter to spin aircraft to allow deviations and increased flow.
