Online order was straight forward. Went to collect the items from GSF Car Parts Heathrow. The Indian male staff member served me was very polite with good customer service. He was professional and deserves 10/10. However there was another white male staff member who was rude to all his customers. Instead of saying next please he said 'come on then'. His face was grumpy as if he didn't want to be there. He was sarcastic to one male customer who didn't understand the returns policy, he was giving him alot of attitude. The customer was swearing in his sentences which doesn't make it right but had the customer been given time to explain the returns procedure correctly and calmly he would not got upset, especially to get called to his desk to say come on then. 1st time to purchase from this store and the experience was terrible to witness that staff members attitude.
