Client had me implement an exit intent modal on their website, inviting visitors to sign up to their mailing list when they moved to close the browser tab.

Client then had me implement an on page load modal which displays the poster for their upcoming event.

Client just emailed "Double popup happening!" with a screenshot of their website with both modals displayed at once.

Kicking myself for replying and explaining that this was expected behaviour in light of what they'd asked for instead of responding, simply, "Yes".
