With Google testing out the "see also' feature on GBP's, someone can be looking directly at your local listing on Google, maybe because they searched for the company name, and Google can be suggesting competitors right under your listing. This has been spotted and reported by users on the platform X (formally Twitter). Although it seems harmless this could potentially redirect potential and existing customers directly to your competitors, just by clicking through "see also". There is no word on whether or not this feature will be implemented world wide.
