Last week Costa Coffee announced it would be opening 32 branches for coffee, food and other drinks across the UK.
It is one of many chains making a slow return, with McDonald's, KFC and Burger King recently announcing plans to reopen select stores and limited menus.
Costa announced some stores would be reopening for drive-thru only while others for delivery.
However, as stores opened this weekend, social media was flooded with people complaining of long queues in several Costa Drive-Thrus, reports Manchester Evening News.
Posting on social media, one user wrote: "@CostaCoffee is it essential that a drive-thru coffee should be open?
"Sittingbourne drive-thru encouraged people to make unnecessary journeys and caused horrendous congestion."
Responding, the official Twitter account for Costa Coffee set the record straight.
Replying, they confirmed: "Our number one priority is the safety of our store teams and customers.
"In line with the re-opening of a small number of drive-thru lanes and delivery stores this weekend, we’ve ensured strict measures have been put in place aligned to Government guidelines.
"We'd like to reinforce that our-drive thru lanes are open to offer key workers the chance to enjoy a Costa on essential journeys, whilst our delivery stores allow customers the opportunity to order a Costa from the comfort of their own home."
