::RESPONSE::
The Office acknowledges that a courtesy flush is, in nearly all configurations, both available and free of charge.

An advisory panel was convened to determine whether voluntary mid-event flushing could be encouraged through signage. The panel reached 0% consensus. A second panel was convened to review the first. It has not yet adjourned.

Your experience is validated in full. It is real. It is recurring. It is, as you note, occurring on a predictable schedule. Regrettably, identification of the responsible party falls outside this Office's jurisdiction and into the Department of Things Everyone Knows But No One Will Say.

::DETERMINATION::
Escalated to Pending, where it joins 4,051 related filings. No timeline for resolution exists. A scented placard has been requisitioned and denied.

::STUB:: Courtesy Flush Notice- Flush Frequency Advisory
This has been noticed.
An event attributable to you has been formally logged. This card is provided as a courtesy, in lieu of confrontation, which the Office does not endorse. Please find indicated below the nature of the matter:
[x] Insufficient flush frequency
[x] Predictable post-lunch timing
[ ] Disregard for posted decorum
[ ] Audible, yet unaddressed
No reply is required. No reply is wanted. Carry on as though this never occurred — as you were always going to.
