A swagger stick not sure but don't think so.
Going back as far as WW1 and before all other ranks carried a Swagger Stick at times, usually about two feet long and in many cases made of Malacca cane.
The Sgt's Mess belongs to the RSM and that includes any by-laws he may introduce. Visitors are expected to respect such laws, seniority doesn't come into it at any level. I never was in an Army mess that said the RSM had to be served first, frequently he wouldn't even be there. Any visitor of any rank that said there would be trouble if a beer wasn't produced within thirty seconds would most likely be invited to leave. In the Army a Wo's & Sgts Mess is just that, not some glorified RAF corporals club!
