Logical drawing

habit already set
    separate till logins, not one shared code
    lock the screen when stepping away
Saturday, second café, queue at the door

    +-- "only this shift" is the exception the habit forbids
    +-- a borrowed login attributes sales to the wrong person
    +-- this lesson does not issue a new login on the spot

Learning outcomes

After this chapter, you should be able to:

  1. Refuse a one-shift return to the shared till code.
  2. Keep screen-locking in force during a queue.
  3. Hold any new login until it is that person's own, not a borrowed one.

13.1 The queue is the case the habit was for

Kwame replaced the shared till code with separate logins, and he told staff to lock the screen when they step away. On a Saturday the second café is queued to the door. A colleague asks for the old code "only until the rush ends," because finding a personal login feels slow. The rush is when a borrowed session does the most harm: a void, a refund or a card report would sit under someone else's name. Kwame refuses the old code. If a person has no login yet, they do not inherit a colleague's. Creating one is a separate step, not a shout across the counter. This lesson does not create that login.

13.2 Worked example

Lesson table; scroll horizontally to read all columns →

Request during the queue What the record would show Decision
"Use the old shared code for an hour." One code, many people Refuse
"I will finish this order on the screen the other person left open." Sales under someone else's login Refuse the borrowed screen
Lock the screen, then unlock one's own login The habit, on a busy Saturday too Accept
"Write me a personal login after the rush." A later account, not this sale That waits. This lesson does not issue it

Synthetic case. The colleague at the second café is unnamed. The example refuses a borrowed screen and adds no person to the staff file.

Errors and limits

A refusal at the counter does not open an account. A personal login still needs the owner's agreement and a notebook line before that person works the till alone. This chapter also does not divide the twelve staff between the two cafés.
