actually it's a huge issue. we had to use a non-good tech stack credit card provider that constantly went down becuase they were the only ones who would take us because we sold tobacco. No braintree or auth.net just some janky stuff from the 90s because that was the only company that fit our risk profile.
The amount of times we got paged because we coudlnt take cards was ridiculous, because we couldn't ever do anything about it.
