Cashier was one of several jobs that did not fire me
Restaurant retail sales
Cashier is better than, sales
Cashier is still bad
But you have to work somewhere
"Beggars can't be choosers"
In some cases, cashier could be the least wrong job
The solar system might not contain your ideal job
If it did, your ideal job, is also many peoples ideal job
And some of those people, have better skills or personality than you (based on the employer)
Not many people work their ideal job
They still work jobs
