The National Post reports in its Saturday edition that thin, leaky and defective are a few of the adjectives that have been used recently to describe Tim Hortons cups, with some customers going as far as to deem them the "worst coffee cup you can get." The unbylined item says that social media is rife with complaints about the cups, which are said to collapse and disintegrate shortly after purchase. Catherine Nasiopoulos told CTV she filed a complaint with the company in February after her cups "collapsed more than 15 times in the last two months," adding that the Tims outlet where she bought them said they never heard of any issues. "Tim Hortons cups are thinner than public bathroom toilet paper and almost always leak," one customer posted to X, calling them the "worst coffee cup you can get." Complaints can be found dating back several months, with some customers saying the bottom of the cup splits after about 15 minutes, while others have had issues along the vertical seam. Tim Hortons did not respond to a request for comment. Last month, however, the company announced it would be testing plastic-free and recyclable hot beverage lids in all Tim Hortons locations across Prince Edward Island for up to 12 weeks.
