He’s seen it all, heard enough, and has absolutely no time for your nonsense. The Caution: Grumpy Old Man – Seek Advice Elsewhere Desk Sign is here to do the talking, so he doesn’t have to (and let’s be honest, he wasn’t going to anyway). Measuring 28cm by 20cm, this fun novelty gift is perfect for marking out Dad’s or Grandad’s territory - whether it’s a desk, shed, garage or ‘his chair’. It’s a not-so-subtle hint that advice, sympathy, or small talk is not available today or tomorrow. Ideal for birthday gifts for Dad, a top-tier funny Grandad gift, or one of those old age joke gifts for men that hits just a bit too close to home. This sign is the perfect combo of useful and ridiculous - because deep down, they love the attention (even if they grumble about it). Just place it where it can be seen and prepare to hear “about time too” followed by a dramatic sigh.
