Non existent training on tills, runners rude & dismissive - Avis employé Customer Assistant - Checkouts ASDA

Giving a massive 30 minutes of till 'training' then left on your own. When ask runners to help they are very rude and short. Won't take the time to show you gift cards/vouchers and then get irritates when you ask. Makes you almost scared and definitely embarrassed to ask! Absolutely shocking.
