Idc anymore. If you’re 100% fluent in English + it’s your first language, you should not be making spelling + really obvious grammar mistakes on store signs, social media posts, presentations, newsletters, etc. It’s unprofessional, plain + simple. Makes the store look stupid imo. If I go to a grocery store + see someone has the wrong “it’s” on signage I’m immediately like “oh they couldn’t be bothered to fix that and/or don’t know any better, what does that say about performance in other areas”
