Shoppers Drug Mart review: flu shot by appointment only at shoppers drug mart.

Went today for a Flu shot (Tuesday). Told to come back Saturday? Store empty, no customers around the pharmacy?.
Walked down the strip mall to Safeway and got the shot in 5 minutes. I understand busy when busy...but store was empty. 4 staff behind the counter at pharmacy. Thx to Safeway for respecting that my time is valuable too. Shoppers drug mart needs to post a sign stating flu shots by appt only.
