Below is the list of tables from the database along with their columns and datatype. Need to generate an accurate SQL query for the question.
Only use the columns present in the respective table. Only use the columns which are required to generate the SQL query. Only use table joins if required and not otherwise.

### Tables ###
TABLE: CREATE TABLE payment ( customer_id VARCHAR )
TABLE: CREATE TABLE customer ( first_name VARCHAR, last_name VARCHAR, customer_id VARCHAR )

### Question ###
Which customer, who has made at least one payment, has spent the least money? List his or her first name, last name, and the id.

### Accurate SQL ###

SELECT T1.first_name, T1.last_name, T1.customer_id FROM customer AS T1 JOIN payment AS T2 ON T1.customer_id = T2.customer_id GROUP BY T1.customer_id ORDER BY SUM(amount) LIMIT 1
