Bad in-store experiences cost the up to £41 billion in lost revenue, according to a leading market researcher.
Forsta found a staggering 80% of UK adults exit a store without buying something if they have a poor experience.
After analysing 50,000 sources, it found 76% of negative online reviews were about bad and 13% of which were down to negative staff interactions.
Kyle Ferguson, CEO of Forsta, said: "When customers are frustrated in-store, they're more likely to abandon their purchases and take their business elsewhere."
Despite the heavy investment into technology - 80 percent of the population purchase goods online according to Statista - Ferguson believes the high street should still be a priority.
He said: "While we're seeing many retailers focus on improving their online experience, the reality is that conversion ratios are fundamentally higher in-store, so retailers must reconsider how they manage their in-store environments."
Rhiannon Picton-James at the Independent believes it's down to Gen Z, revealing her frustrations in a piece titled "Gen Z are terrible at customer service - and it's killing the high street".
She said: "If the UK high street was already dying, this current generation of young shop assistants have slapped a 'DNR' on it."
A survey by ResumeTemplates in the US found 1 in 4 companies reported losing customers because of Gen Z employees' behaviour, noting some lacked the ability to effectively interact with customers.
Among 1,000 hiring managers surveyed, the top concerns for Gen Z in customer-facing roles were an unprofessional tone (41%), poor attention to detail (40%), lack of initiative (39%), and low enthusiasm (38%).
Picton-James added: "This is an online generation, the first to grow up on the internet and their identity is defined by their digital experience - and Covid-19. Some of their customer service, and social skills, are godawful."
However some disagree, with @madisontayt_ commenting that Gen Z are no different to other generations on X: "It's high time we all start admitting that, largely, millennials/gen z aren't any less insufferable and entitled than boomers when it comes to customer service."
Another user @Arap_Nyasikera said: "This group has unparalleled energy and resilience. But it requires a change in perception about employee culture. First, they aren't boot-lickers and their loyalty is hard to come by. But they adopt technology and digital tools faster than any other generation."
Customer service wasn't the only problem according to Forsta; queue management also contributed to 19% of negative reviews.
