title: Laravel S3 random mime type
body: <p>This is very weird, i'm trying to retrieve an image from AWS S3 form Laravel controller but i get a random Mime type on every reload.</p>
  
  <p>Code in controller</p>
  
  <pre><code>public function show($attachment){
      $attachmentTest = Storage::disk('s3')-&gt;get("attachments/".$attachment);
      return File::mimeType($attachmentTest);
  }
  </code></pre>
  
  <p>And the router:</p>
  
  <pre><code>Route::get('attachments/{slug}', [
      'as'         =&gt; 'images.show',
      'uses'       =&gt; 'AttachmentController@show'
  ]);
