These notes name a sitting at Mentis Beacon. They are letters we asked to print, edited only for length. They describe a receipt, a column, or a morning at the table.
A morning on the train
Daniel Cho came for the Saturday table
Daniel works in Seoul and had been asked, more than once, to explain Solana fees in an internal meeting. He was improvising from a wallet screen. On 6 June 2026 he took the train to Goyang for the four-chair table.
Minjae Park held the group on the first sample until every chair had written 5,000 lamports for a single signature. Daniel later said the wait annoyed him. The second sample then showed a priority fee on a transfer of the same shape, and the subtraction finally had somewhere to go. The following Monday he used that order in the meeting: signature line first, extra fee second, held SOL left out of the fee entirely.
He did not bring a personal receipt. Saturday never asks for one. His practice sheet went back on the train; the library samples stayed in the folder.
I brought a transfer where the priority fee was larger than the signature line, and I had been telling my brother the whole total was a tax. Hana covered the total with a card until I had written 5,000 lamports for the one signature. The middle column took the rest. I still have the pencil smudge on that sheet.
The second visit did what it promised: a new receipt, the same three columns, done inside forty minutes. I wish the worksheet had a blank row for the compute-unit limit, because I had to write that figure in the margin and it looks unofficial. The split between the fee and the SOL sitting in the account is clearer than anything I had managed alone.
I had a printout from a slot that included two signatures and no priority fee. I kept adding the signatures together as if they were a percentage. The desk made me write two rows of 5,000 lamports and then stop. Short visit in spirit, full seventy-five minutes on the clock, and I needed the time.
Your receipt can be the next one on the blotter.
Reserve a window desk if the printout is yours. Ask for a Saturday seat if you want the shared samples.
