Case records
Read each record on its own terms. A claim made by a person is different from a fact established by an independent record.
LINKED RECORD
Order stub
The order checked in three coats and paid with a 20-credit note. No other items were checked in.
This supplies quantity and payment.
CONTEXT NOTE
Peg plan
The coats were placed on pegs 8, 9 and 10.
Peg numbers are storage references, not prices.
PRIMARY RECORD
Cloakroom tariff
Each coat costs 4 credits. A single 3-credit order fee is added once to the whole order, regardless of coat count.
This distinguishes the per-coat charge from the once-only fee.
