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 Payments ( payment_id INTEGER, booking_id INTEGER, customer_id INTEGER, payment_type_code VARCHAR(15), amount_paid_in_full_yn VARCHAR(1), payment_date DATETIME, amount_due DECIMAL(19,4), amount_paid DECIMAL(19,4) )
TABLE: CREATE TABLE Bookings ( booking_id INTEGER, customer_id INTEGER, booking_status_code VARCHAR(10), returned_damaged_yn VARCHAR(40), booking_start_date DATETIME, booking_end_date DATETIME, count_hired VARCHAR(40), amount_payable DECIMAL(19,4), amount_of_discount DECIMAL(19,4), amount_outstanding DECIMAL(19,4), amount_of_refund DECIMAL(19,4) )
TABLE: CREATE TABLE Products_for_Hire ( product_id INTEGER, product_type_code VARCHAR(15), daily_hire_cost DECIMAL(19,4), product_name VARCHAR(80), product_description VARCHAR(255) )
TABLE: CREATE TABLE View_Product_Availability ( product_id INTEGER, booking_id INTEGER, status_date DATETIME, available_yn VARCHAR(1) )
TABLE: CREATE TABLE Discount_Coupons ( coupon_id INTEGER, date_issued DATETIME, coupon_amount DECIMAL(19,4) )
TABLE: CREATE TABLE Products_Booked ( booking_id INTEGER, product_id INTEGER, returned_yn VARCHAR(1), returned_late_yn VARCHAR(1), booked_count INTEGER, booked_amount FLOAT )
TABLE: CREATE TABLE Customers ( customer_id INTEGER, coupon_id INTEGER, good_or_bad_customer VARCHAR(4), first_name VARCHAR(80), last_name VARCHAR(80), gender_mf VARCHAR(1), date_became_customer DATETIME, date_last_hire DATETIME )

### Question ###
How many bookings did each customer make? Show the customer id as the Y-axis and the first name as the X-axis in a bar chart, rank from high to low by the X-axis.

### Accurate SQL ###

SELECT T1.first_name, T1.customer_id FROM Customers AS T1 JOIN Bookings AS T2 ON T1.customer_id = T2.customer_id ORDER BY T1.first_name DESC
