Moogle probably works in California. I doubt pharmacists verify 500+ a day in California because of 1.5x OT, strict counseling requirements because of active BOP, and Kaiser is a big player in California, i.e., those patients stay in Kaiser and generally don't fill cash scripts at outside pharmacies.
I can't think of a single non-24 hour CVS in northern California that sells more than 2500/week. Definitely not in the Sacramento area. There is exactly one 24-hour CVS and two 24-hour Walgreens in the greater Sacramento area (~2 million people). To my knowledge, CVS still doesn't take Anthem Blue Cross Medi-Cal, a multi-county managed care Medicaid plan, anywhere in the state (neither does Walgreens), so those patients go primarily to Rite-Aid and Walmart. Southern California has more 24-hour locations but they still have Kaiser too.
I am sympathetic to situations like ancienbon is in. There is no legitimate reason to provide minimal overlap. One reason I quit CVS is because of 13-hour shifts (used to be 14) w/ no overlap doing 2500-2800 sold a week for 8 months and they didn't even bother hiring a FT pharmacist for almost a year. The RPH "budget" was 86 hours for an 82-hour store. At CVS only the pharmacist is supposed to fill CIIs, so there you go, the RPH is filling at least 60-80 Rx minimum.
